I've only had one bad experience with eBay. The seller described the razors as Bright Shiny and excellent. THere were 2 in the one sale. I was really interested in "A", but "B" was in pretty bad shape.
I gave him a less than perfect rating for item description.
He emailed me a nasty gram that said I should have contacted hi first and asked for my money back. I told him he should have described the razors more appropriately. I guess I screwed up his perfect 100% rating... Actually HE screwed up his rating.
