I have only returned a few items in my whole life and all of those because of product defects. Flip side: my brother returns many items every month and I am surprised that he does not get, somehow, blacklisted as a customer. He does spend a lot on consumer items so maybe he has not tripped a bad customer alarm because of the large volume of stuff he purchases.

My question is how much do consumers like my brother cost consumers like myself due to increased costs? My brother is a great guy and I hope that I don't sound like I am dumping on him, but it would be nice if customers like me got some sort of discount.
