It happened to me twice in the last few months. I would place an order with a seller on amazon market place and the seller would cancel the order with the excuse of "out of stock" while the item is still showing offered by the same seller on amazon at a much higher price.
I filed a complaint with amazon.com and called customer service with no resolution. Amazon.com customer service said they can do nothing about it. The order even disappeared from my order history so I did not get a chance to leave an appropriate feedback.
I think amazon.com is morally responsible for policing those sellers and making sure they do not cancel the order because they found out they can sell it for more while amazon.com allows them to continue listing it as in stock.

Amazon provided poor support and charged me for the return when their web page provided incorrect data.  When I wrote 2 reviews they did not post them but posted only glowing product reviews or positive reviews of themselves.  I'll never shop there again.

Amazon lists items as "In Stock" (in green bold) they do not have to sell.

Amazon offers delivery "Estimates" they can not achieve.

Their Customer Service replies to complaints with form emails telling you how they can't control anything.

Think they are too big to fail even with lousy service.

DON'T SHOP Amazon!!

As a potential future merchant.  I signed on for Amazon's free trial for their merchant services.  Finding that it was a bad match for my particular needs, I cancelled within the free window.  I received a polite email stating that I would not be charged and thanks for trying, etc.

On my next statement, I was charged.  Fine, these things happen.  I wrote to Amazon, and to my credit card, the charge was removed.  This was August.

In September, I was charged twice, and again in October. 

I've written them again, but am scared to death, I'll have four charges in November.

Wish me luck!

Amazon has various arrival times. However has excellent return policies. Amazon is an excellent option, as far as online stores go.

I've been a long-time customer of Amazon and have generally been willing to pay a little more for the convenience of Amazon's site.  That is until now.  I'm spending some time overseas and therefore, thought I'd try the Amazon International ...

 I have never had a problem getting my items on time, making payments, or anything!  Amazon is a very smooth process and I would recommend them to anyone.

I bought a PS3 slim off of Amazon Marketplace for $230 only to have the seller cancel my order the next day. The reason the e-mail listed was because the seller could not ship it to my address. I just bought something a week ago from Amazon and the seller had no problem shipping to my address. The real reason was because the seller did not like the price he sold it for so he canceled my payment and re-listed the item for $299. I called Amazon and they said because it was a Marketplace sale the only thing they could do was give me a $10 rebate. The problem is, because I thought I bought a PS3 Slim, I sold my original PS3 and now I have no PS3 at all. So now the seller gets to sell their item and gets no negative feedback or anything. It makes no sense that someone is able to sell an item and then cancel the sale because they aren't happy with the price they sold it for. I will no longer be doing any business with Amazon.

My three children recently received three $25 gift certificates.  What does that mean to you at amazon?  You know, when 90% of their items don't qualify for the "free shipping saver".  It is really hard to explain to a seven year old that they only really have $12 because the rest has to go to shipping and handling.  They spent the $75 (in one order) and paid $46 in shipping in total to four different merchants.  Only one item qualified for "free" shipping.  When they are being shipped from different sources you pay shipping to the individual supplier.  Amazon is just another money grubbing middle man.  
Two items arrived in 3 days.  One took 5 days.  The last two weeks.  Shipping time?  Hard to judge and it's not like Amazon can fix it.  They don't actually do anything, but take your money

I recently ordered via Amazon a Plantronics Voyager PRO Headset AMAZON ORDER NO: 002-9356880-5164257. August 6, 2009 It was shipped by VibeCellular. It arrived August 11, 2009 in a small mailing envelope. Inside were two plastic ...

Amamzon Marketplace (jewlery section) acts as a monolpoy and only allows a few companies to sell there. They have a LLC that aproves the jewelry Marketplace sellers and if you dont have 2,000+ products they deny you. Now if you want to sell in other sections they let anyone sell.

regular amazon is great amazon marketplace has issues. I agree with other just buy directly from the companies and avoid the marketplace.

MANUFACTURER MAY NOT HONOR WARRANTY ON ITEM PURCHASED FROM AMAZON: Do your research on every product, particularly about warranty. Many NEW products sold directly on Amazon Marketplace (not from a third party) are NOT honored for warranty by the manufacturer. Clarisonic is an example. You will get burned if you purchased such an item on Amazon.
RETURN ITEM AND AMAZON WON'T REFUND claiming not item sent. We purchased DVD set sealed as a gift. We had to return the same set as person already had it. Amazon argued the item was not the one sent. Yes, in fact it was! Moreover, Amazon didn't bother to return that item back to you. Amazon wouldn't refund our money. They just kept the returned item AND our money! We had to fight it in court and with the credit card company for months to get the refund owed to us by Amazon.
REFERRAL TRACKING doesn't always work.
Finding out that referrals are not paid during system problems. This was verified to us. There is no level of trust with this entity.
We do not shop with Amazon any longer.

I've been shopping at Amazon for a long time. This is the only site that I could trust since they rate the sellers. I have never had problems with them. Once the order did not arrive so I called and they reshipped another package to me. Within 2 days I received it. The quality of the shipped products is in excellent new condition. I'm happy with their service.

I find online prices to be lower than local retailers. It's interesting to see the large price differences, even online, for the exact same product. Shipping is prompt but can sometimes add considerably to the cost of an item.  I always check out free shipping options first.

On a Saterday afteernoon, I searched for a book.I was amazed it only took a minute to locate, than the computer walked me through and customer service was great.I would shop there again and again.There variety and there easy to use web site with very good hyperlinks were amazing.I called all  my friends and family and told them where to shop.When i finally recieved my order <IT ONLY TOOK TWO DAY>
I was very pleased they offered a 100% satisfaction on the correct order.from the computer to the door was only two days> come on you gotta try AMAZON MARKETPLACE.I did.

Vendors beware! If you want to associate your business with Amazon - think twice! The interface which registers customers on Amazon is horrible. A week after you dont receive what you ordered it forgets you ever existed. It happened to me twice: once with a laptop battery and once with the car part order. Shopping on Amazon has been my worst experience and I shall NEVER buy anything from them.

worst place to shop , nast customer service, buy from the direct sellers here on shopping dont touch amazon or ebay or buy.com

I ordered a Garmin GPS from VibeCellular.com which is part of this amazon marketplace.  When the order was placed I received an email that my order would ship within two day.  I waited three days and heard nothing more from them so I tryed to call but of course they will not answer their phone.  I emailed them and received an email back that I would be receiving my GPS on the following Tuesday.  That Monday I received an email from them telling me my order was cancelled (the day before it was supposed to arrive). 

I don't know how most of you feel about this sort of thing but I dislike being lied to and taken advantage of.  I needed that GPS for a trip and they left me hanging and on my own to go out and buy one at a much higher price at the last minute.

I would never suggest anyone buy anything from VibeCellular and I hope they go out of business!

Remastered CD came with big greasy thumbprint on it. Was someone eating fried chicken while they were packing it? Didn't even want to put it in my player.

Amazon is really amazing. Great selection for customers and quick delivery. Customer Sevice is helpful and excellent. I always enjoy my shopping at amazon.

I've lost money at two separate marketplace stores, caimon and wicked wolf press. Caimon backordered the item until my time ran out, then ignored my many emails requesting status.  Wicked Wolf Press put me on hold to "look into it" and I haven't heard back yet.  Additionally, you pay up front, instead of when the product ships, but it takes longer for processing and shipping, yet you are still paying for 3 to 5 day shipping.


UPDATE: Since I put this opinion in place, Wicked Wolf Press made good on my order, so I've only lost money on Caimon now.

it was an awesome experinence shopping with amazon.. the Quality of goods is very good. Selection is as i expected is very huge. Delivery is fast. Customer service is helpful.

Amazon Marketplace is an off-shoot from the original Amazon web-site, which allows many different sellers to provide products that Amazon customers might find to be useful.  Where Amazon has quite a wide database of products, they cannot sell every ...

Having anguished over the selection of a small network enabled color laser printer, I final chose the Brother HL-4040CN.

Next was to find the right price from a reputable supplier. Via Epinions, I visited the Amazon site and found the printer was being sold through an Amazon.com "trusted seller", esellerutrust, at one of the lowest prices available on the internet. I placed my one-click order.

Three days later (several days earlier than anticipated), my printer, which was received excellently packed, was up and running.

I have never had a bad shopping experience with Amazon.com, but even I was impressed with the efficiency of this order.

I placed an order for a book I needed for class. The statement at the bottom said "Usually ships in 10-12 days". I thought they were leaving themselves a wide window but it would probably arrive on time for class. That was Jan 12. Today is Jan 30 and I find out that they did not have it in stock and had to special order it. When I spoke to customer service I asked why the web site didn't tell me the book was not in stock and had to be special ordered. Their response, well it said 10-12 days for shipping. So, I was supposed to know that, right? If they can say that an item is in stock why can't they clearly say that it is not in stock and will have to be ordered? Put simply, marketing deception. I will avoid doing business with Amazon in the future and look to a company that has more integrity in dealing with customers.

I always trust Amazon! They stand by their products and merchants.

I've  had small problems in the past but their customer service people were always willing to help.

I buy almost everything at AMAZON!

Amazon is incredibly fast to ship the product. We always have a great satisfaction by ordering there. Their choice is bigger than any merchand and I hope to order to them soon.

Amazon is a rip off for all sellers, they freeze your funds randomly and have a team in India called Alliance that deals with suspension and they suck: Broken english, conflicting reasons, Class law suit to start in MA but need 3 more victims of Amazon Alliance abuse. Email me if interested mailto:audioclicks@gmail.com

The best on-line marketplace...better than ebay since they police the bad apples and ebay takes longer.  I've never had a bad experience with them.

I attempted to place an order with one of Amazon.com's Marketplace Stores. I put 14 toys in my cart totaling $100 and they were going to charge me almost $72 in shipping costs! It turns out that most of the stores at Amazon charge on a PER ITEM basis rather than a PER SHIPMENT basis. How do they legally get away with this consumer rip off? I called Amazon customer service and their only advice was to contact the seller directly. I don't think Amazon should let their sellers get away with this. Shame on you all!
