Can I restrict quantity one buyer can order at a time without changing total in inventory?
I want to run a promotion that offers a sale price on certain items but I don't want an individual customer to be able to purchase more than 10. I can change how many I have in inventory, but that prevents the possibility of other customers ordering up to 10 if I can't change the inventory fast enough. Suggestions on how I can do this? Can I restrict a single transaction from ordering more than 10?
