Buyer's remorse is the #1 reason most of these guys try to come up with some BS excuse on trying to return an item. That reminded me of one other incident. I sold a set of '65 or so Thunderbird chrome headlight trims. They were rough, and they didn't go for much, but I didn't have a smart phone at that time, so I couldn't look them up from the yard to see if they were worth picking up. One of the trim pieces had a slit in the chrome on the inside where it can't be seen. I made very clear mention of this in the auction, AND it was showing in 3 pictures, including a close up of the damage. Guy gets it and says I owe him a refund because I didn't mention that part. Pointed him out to the exact quotes from the auction and which pictures it can clearly be seen in. He didn't respond. Again, luckily no claim filed or negative feedback left, but it's very irritating to have to deal with such douchebags and hope that nothing negative comes of it.
It sucks that eBay has given an out for people with buyer's remorse, but all in all, I've still made some nice spare change on there, so it's not all that terrible. I just wish Google or someone would come along and finish off eBay. Whenever I say this, I get some people that are like "companies have tried that in the past, and failed". To that, I retort with those companies (Yahoo! Auctions, Ubid, etc) tried at the wrong time. They tried to take a piece of eBay's pie while eBay was at the pinnacle of its popularity. Now, everyone hates eBay, so those pieces are ripe for the taking. Now is the time to strike.
