As someone who has been buying and selling on ebay since 1998, what you say here is a problem. Once an auction has ended, both buyer AND seller have entered into a contract. Buyer to pay a specified amount, including any listed shipping fees, and the seller to deliver what was sold. Granted, it's only $5.25 and I was refunded, but the seller breached the contract.
Additionally, I don't know how they could include Topps, Donruss, AND Fleer rack packs for it to be only 70 cards. Two rack packs make up the 70 cards, not 3. The listing sure looked like 70 rack packs.
Anyway, I am comforted in the fact that I did get my money back, that I didn't get something I wasn't expeting, or any of that. I do, however, think this is a very shady business practice. If I didn't send out stuff I was disappointed in the amount realized, I'd probably have only sent out half the items I've sold! (And I'd be kicked off ebay.)
