Hey, realistically, yes you can ask her to pay for something she doesn't need, a dispute will be raised, she will be banned from ebay and you wont get paid for either item. Alternatively, (this is if you are using paypal only and i would suggest this is the only payment method you use). Request her email address for paypal account, go to paupal, go to create invoice, input the price and in the notes what it is for, who it is from (use your ebay user id) and copy any reference numbers you are given and relist the other item.
