Your bid is a contract. Expect to be perma-banned from Ebay.
Simple. Inform eBay you are 13 years old. Since their rules state you must be 18 the account will be closed. Better get to it before any card/bank account attached to it gets charged.
The best thing you can do is contact the seller but i think you better let the person who's account you're using know what you've done and let them deal with it. This could cause negative feedback.
That should mean that your highest bid is $400. So you only have to pay that much if other people bid it up that high.
You can retract your bid if the seller agrees to allow it. Just contact them, be polite and explain in detail your mistake
if the account you are on has a active credit card then yes it will charge it and you will have to buy it lol not to sure you can cancel a bid
