The drug discount cards are used in participating pharmacies. The pharmacy negotiates a discount with the card companies who provide the pharmacy customers with discount programs that reduce the cost of their generic drug or brand-name drug prices. The pharmacies are then charged transaction fees every time a customer uses one of the card programs. The pharmacies do it because they want to do all they can so their customers come to them every time they need to fill a prescription for generic medication or any other type of drug.
