I wouldn't be suprised if you don't get reimbursed or have the merchandise shipped to the buyers. Wouldn't mind seeing some people who has actually done this.
Lemme guess how this works.... a sukka signs up with your "service", and post a bunch of auctions on Ebay. Said sukka collects all the payments, then sends bank wire to your offshore bank and you promise to send out the good "right away". Is that about right?
