Dan,
Don't get me started on shipping fees. One of my pet peeves. I don't mind paying for what I get but I hate getting cards in a letter envelope with a stamp on it after paying $3 to $5 or more in shipping fees. That drives me nuts. I peruse ebay looking for bargains so when I find one, the seller trys to juice his pockets by skimping on shipping. It doesn't happen a lot, most of the sellers are pretty good about shipping especially since ebay enacted the newest feedback system where you can rate the shipping costs.
oh well, of my box. Back to the point. I have not sold a card on eBay in a long long time. 2 years maybe. I buy cards off ebay weekly and would hate to see that avenue die off. Another note, I did recently sell on old laptop on eBay. Things went flawless so its still a great way to hock your wares.
