Refunds are given if the item is returned within 60 days, and they will give the refund back to you in the same form of payment (e.g., cash for cash, credit card for credit card). If you don't have a receipt, they'll try to verify the return if it was made with credit/debit.
Not sure but if you pay with card you do not need the receipt for the item you can simply return it granted it works and is not missing anything
