In my case, it was posted in auction as 'actual charges', which it wasn't, and the item was not received safely (worst packaging I've ever seen). And according to the seller, that wasn't a reason for a neg. Ahem... right, okay buddy. But anyway, that was my experience, not the OP's.
I recently got in a complete control panel for an arcade game. The thing was packed in newspaper barely and was charged $29 for shipping. the actual was like $10. I still wasn't upset at all as the item worked fine and I knew the price when I bid. I left great feedback and all 5 stars.
Got my item, knew what I was paying, item worked, good feedback left, end of story. I was grateful to get that hard to find item that I could never find without ebay.
almost got a similar story...ok maybe not but i bought a "brand new" psp screen (the screen was 20 the shipping was 15 and it came in a tiny flimsy box) on ebay for my friend and the thing didnt work
so of course me i take it apart and sure enough the back light was dead in it
i switched the back light with the an old one and it worked just great but even after all that i still left good feedback because all i needed from him was the screen ^_^
what im trying to say is people abuse the feedback system
