"I wish I could give you a refund but because your item was already sent to you the best I can do is send you either another sweatshirt or items of your choice. Let me know what you'd like to do."
This time last year, I ordered a few CDs from a website, never received them, and was issued a refund. However, I paid for the sweatshirt with Paypal and the CDs with a debit card. I don't know if that makes a difference. Do I have any ground to stand on here?
