Frustrating to have bought $500 of your coupons, receive in return 10 or so cards (!), which won't fit in my wallet and were, of course, lost. So I was unable to use those toward a $250 haircut yesterday and am wondering if I forfeit the $500?
May I suggest a more streamlined and realistic way of distributing your coupons, i.e. on one card? It seems you have a computer system that includes one's salon history, so perhaps that could be at least a back-up source?
