I offer a unconditional return policy. I just say they pay return shipping and I don't refund shipping costs they paid in the auction. I have had 2 returns in 5 years. Here's the thing, ebay or pay pal are going to force you to give a refund no matter what if the buyer wants one. I figure I will offer one and increase a buyer conversion AND some people will ask return something and if you don't give them a fight they forget to return it and you don't have to give the refund. If you fight them, they are more likely going to make sure you get the item back AND give you bad feedback. I don't care what other sellers do, but I would be more likely to buy from a seller that offered a return policy. In fact if the listing says specifically NO RETURNS I click back and find the same item from someone who does.
