Richard,
I will take this one based on two things I hope you will agree to.
1) You will give it to the first customer in the store you're working at on Saturday. Explain to them the coolness of Bronze Teen Humor, Romance, Westerns and other lesser collected genres.
2) Take the extra payment (already sent through PayPal) to buy your staff pizza and drinks tomorrow for lunch (or dinner). I'm not sure how many people you'll have in the store with you. If there is money left over, send a pie to another store or two.
It's not much, but hopefully it'll take your mind off things for a little while.
