how do i cancel an ebay bid?

[Death Blade]

ok so basically i thought i had more money in my accounts than i actually did, and the minimum money i could wager for a bid was more than what was actually in my account. and i had just found out after to see exactly how high i could bid if i get outbid. now who can i contact or how can i cancel my bid on the item in case i don't get outbid?[like i said i have less money than i thought i did in my account]

you can not cancel a bid.

if you can not pay if you win you will be thrown off e-bay and not allowed back
