Amazon Marketplace Amazon sellers ignore winning bids, sell same items to others Internet

Two times I tried to buy a used laptop from individual sellers.  I accepted the asking price and each time the sale went thru with a delivery date.  Both timess, after receiving no shipping confirmation by the promised date I contacted the sellers.  The first seller responded "I sold it to someone else."  The second seller never responded but continued to list the same laptop at a higher price.  I complained to Amazon which canceled the orders.

I wasn't out of money but it spent several frustrating weeks waiting for the laptops I thought I had bought.  On ebay if seller fails to honor a winning bid there is an opportunity to leave negative feedback. Welching on a winning bid is a serious matter in the ebay community. 

Not so on Amazon.  There is no way to leave feedback unless a delivery is actually made.  Neither seller I ordered from seemed to have the slightest sense of moral or legal obligation to fulfil a completed sale and both continued to fish around for a higher price.  There is no remedy for this failure under Amazon's feedback procedures.

I will no longer buy from individuals on Amazon Marketplace. Don't try it unless you have a lot of time and patience.
