Wanting a receipt can be for so many reasons. I use them to write off the item on my taxes. You need to educate yourself! Do you have a Paypal? You can print the mailing right on your computer and box it up (USPS PRIORITY< NOT PARCEL POST) and they will p/u right at your door. Cool deal. Of course you can say its unreturnable. Next time put; as is and unreturnable. Check all photos and email with questions.

The buyer gets a paypal receipt emailed or can get a copy from their transactions list. It's possible they meant a tracking receipt which you want delivery confirmation for proof of delivery. Without D/C a buyer can get a refund as theres no proof of delivery.

Yes, wanting a receipt and wanting to return the item are not the same.

I am new to eBay and I sold my first item 2 days ago. The person payed and wants a receipt but I sayed in the auction that the item is unreturnable. Do I just say the item is unreturnable?
