I used to work for eBay in the Resolution Center department. One of the reasons why I quit that job (even though it paid well and the people I worked with were AWESOME) was because I got tired of having to explain to sellers on the phone why lopsided policies that favored buyers weren't lopsided at all. I dunno. I just got tired of playing spin doctor all the time. Sometimes I'd just tell a seller straight up, "You're right, such-and-such a policy IS unfair to sellers like yourself".
Some of the complaints I'd get from sellers were pretty ridiculous, though. In my experience, sellers were generally just as shady as buyers. Some of the worst people I had to deal with were sellers. I know selling on eBay is tough, stressful, etc. I've sold a bit on there and don't like it. But yes, there ARE sellers out there who try to cut corners and get away with stuff.
Like this one seller I talked to once...they had sold an item and their buyer had filed a case for not receiving it. My first question to the seller was, "Okay, what day did you send the item?" They replied, "I haven't, yet". I looked at the auction page and saw that he had sold it two months prior. I asked him why he hadn't, and he said, "Because I just haven't gotten around to it". When I asked him why he was upset that the buyer had filed a case, he said, "Because I just kinda feel like, if a person buys something online, they should be patient and just get it when they get it. And they should beware of sellers".
I couldn't believe this guy, and I actually lost my temper with him and closed his case against him, thus refunding the buyer. It's true, sellers as bad as him didn't come around too often, but I just wanted to share that story to illustrate that not all sellers on eBay are saints, and it's people like that that make eBay need to make policy after policy that protects the buyer.
I don't mean to anger anybody, either. I have tons of respect for good eBay sellers. Like I said, I've done it a bit and it's just too much for me. I buy on eBay all the time, though, and I just love honest sellers. It really sucks that there aren't any alternatives to eBay. I'd definitely support an alternative site, so long as they were trustworthy and such.
