http://user.auctions.yahoo.com/user/biddlewicketPuttin' on a bunch of inserts, rookies, and whatnot on Yahoo today...
BIN of .25, shipping .75 = $1
No Paypal (unless you buy a ton) because of their fees.
Will combine shipping (up to 10 cards for .75).
Accept check, mo, cash (send a buck in an envelope).
I'm listing baseball now, basketball after that (mostly Bazooka rookies). Should be around 100 lots.
Why Yahoo? No seller fees!
