commit to buy?

Unfortunately, unless the seller agrees to cancel your bid, you are legally bound to pay for that item. As a former seller, I have had many people do exactly what you have done, went through ALL of the steps of the final transaction include commit to buy, only to contact me saying they didn't mean to buy my item. After hearing this 4 or 5 times from different "highest bids".. it gets old. If the seller doesn't cancel, please go through with the sale, if you get the item, and don't want it, put it up on ebay, try and make your money back. It is a very long, irritating process to try and get someone to pay. That being said, I am not saying anything bad about you. Just sharing my experiences as a previous seller. Good luck, I hope it gets resolved.
