Bidder's Remorse 

When you bid on something on eBay and automatically regret it. Due to this regret you wish to retract your bid, but eBay rules don't allow this. You are left with a feeling of remorse hoping that someone will outbid you.

Sarah: Man, I just bid on a new phone on eBay.

Matt: That's exciting. Do you think you will win?

Sarah: I hope not, I have a bad case of bidder's remorse.
