Is there any way i can withdraw an item from being sold?

My FF7 is up for sale but i regret putting it up

I dont care about negative feedback btw
Then just e-mail the highest bidder and tell them you're not going to sell the product. Don't accept any payments and don't send it. You'll get negative feedback, but you don't seem to mind.

youre an idiot for selling that but if they happen to win you can have a mutual agreement not to finish the transaction
