Fleabay has gone to pot since sellers haven't been able to leave bad feedback on buyers. I used to sell all of the time on there, but out of the ~10 transactions I did in the past year, 3 have ended up somehow screwed up.

(1) buyer claimed that he meant to bid $2 instead of $20, and could he cancel the auction. "Sure, if you pay my listing fees + $5 for the trouble, boy."
(2) buyer never responded
(3) buyer left me bad feedback, claiming an item didn't work. Nevermind that he didn't ever try to contact me -- I'd have given a refund and had it sent back.

Not to mention that PayPal is mandatory for a lot of items now, so you get sodomized both ways. EBay fees and PayPal.
