Agree- A recent little blunder at KQ found me receiving the wrong item (right description, wrong pic on website), so I called CS who said they'd credit me the price of the item (or exchange for the other item- either one was ok for me) AND credit my return postage (which was small, but still)...and to just make notation on the return slip of these facts, and the two reps involved.
I ended up with the price of the item refunded, not my return postage, and no exchange. While I'm glad they at least refunded the purchase price, had they had the right picture to begin with, I wouldn't have had to send anything back...
Yep, it's the little things. As big as they are, they could have gone the extra mile like you experienced. (Heck, it's not even a whole mile!)
