I am afraid that YES, he cheats...2% of the times

I decided to Google for fastmemoryman and the results confirm my worst suspicions.

fastmemoryman is Mr. Chetan Saraf and there are records of his scams all over the Internet:

After reading about him, my conclusion is that he lives in the edge. He is selling very cheap products that are ok 98% of the time and then he has big margins thanks to the remaining 2% buyers that suffers all kinds of scams: Unsent items, partial refunds that exclude inflated shipping expenses, broken items sent, lower quality items sent, ...

Paypal and EBay do not show any interest in getting notice of this evident situation, as they are receiving their percentage of this business. While fastmemoryman manage to keep his rating over 98% there is no problem.

The result is that 1300 buyers were probably cheated last year (negative feedback) and another 1300 had problems (neutral feedback).
