Smart Card Trades Your Many Discount Cards for One
Plenty Card gathers all your discount cards into a single piece.
Discount cards are good for buyer and seller, motivating loyalty for a store while saving the customer money. The drawback to discount cards is that, since 2000 or so, every shop has them. From the vendor side, this reduces the value of having a card. From the customer side, it means carrying a whole bunch of discount cards around…or keeping them in a drawer and forgetting the relevant card when you go out to run errands.
