I guess it's more about trust and maybe marketing than I thought.
The trust thing is obvious. Buy from a trusted seller, but maybe the seller on top has a "storefront" on thebay? maybe he bottlenecks traffic into his buying domain with some clever other ploy...I just sell with clear, concise, detailed descriptions, being aware of what search terms I want to show up in. Past that, I just make sure that all of my stuff gets there and is packed with the best of care. I don't run a business or anything, I just try to make back some of the cash I have poured down the gullet of our hobby's beast.
I mean, I have seen a lot of wide gaps in prices, but never on such small a scale. I've seen auto cards just out go for TWENTY dollars apart in just minutes...but it was $47 and $67. This is a different beast.
I have this card, so naturally I was checking to see what I could get for it once I decide which 2011 prospect B'autos I'm going to keep. I find these auctions. These ended only about an hour apart, and no. not midnight and 1am. more like 4pm and 5pm. I have always been a minimalist stat geek and have a 1041 rating on eBay. I like to think I know how it works (I am sure many of us do) but this stuff just intrigues me.
