10% is $40 on a $400 purchase. I agree that you are better off sucking up the stubhub fees. For example. I sold 3 games of parking passes last year and mailed them to the buyer. I had sent them certified mail and they still got lost by the U.S Mail. StubHub guarantees delivery or they pay for the tickets. I had that experience too and it was SO nice that the reimbursed me.
