After all, he's still on the hook for all but $10 of the purchase price. If I were GameStop I'd get a camera crew together and make this some good press for a $10 "loss".
Marketing like this doesn't get cheaper than $10.
Sadly, finding this sort of initiative in corporate America is rather difficult... which is why folks like e.g. Airbnb eat their PR/marketing lunch.
Except for the fact that Game Stop is stupid and evil. They actually have a policy where they won't let you open up your game in the store after you purchase it for the purpose of exchanging it if it's scratched. Then again, most commercial games these days are designed for really dumb people, so it's not all that surprising.
