It would be better just to have the shops restock like ever 1-2 hours... This would prevent people from "claiming" items in the shops. Such as I see a ring that I can't afford, I go and make money for a few hours, come back, and the ring is gone and I get all mad.

Just make it more like a real shop. If no one is buying certain products, don't stock them as much. If no one is buying a "ring -whatever" then stop stocking it and put something in it's place.
