My girlfriend purchased a game for me (in error - "Punch Out" vs "Mike Tyson's Punch Out") and I called to ask if they had the desired game in stock. I was informed that they would not accept the exchange unless the item was defective. "Mike Tyson's Punch Out" costs about $10 to $15 more so they would be benefiting from the sale. In the end, they lose a regular customer and a sale in one fell swoop.
