It sold for $3.79, and there's another listed for $3.25 BIN...
I don't know anything about that collector world, but maybe that "edition" "series" or whatever was valuable....or the animal charity thing really worked well, or they didn't search to see if there were others on ebay. I've seen that a million times...bidders bidding up an item higher than the amount you can buy the identical item elsewhere on ebay as a Buy It Now...
I too am kinda skeptical that the money will end up in that organization's hands...
