Is there anyway to retract in auction?

Title says it all, is there anyway to retract a bid?

I don't think so. Many times I've seen on feedbacks about "accidental bids" and I doubt the option for retracting has been added recently.
Hope someone will outbid you or that the seller will understand your position. Worst case is probably just one angry seller and negative feedback for you.

i pmed him asking if he will let me get out of the trade if no one outbids me. Man i was in school, i was bored. Who can blame me for bidding on things i dont need!
