How is US Discount Drug Program prescription discount card plan different from traditional prescription insurance?

This plan is not insurance; it is a prescription discount program. The card provides immediate discounts at the pharmacy. Upon presenting your US Discount Drug Program card to the pharmacist, a discount is taken off the regular retail price of the prescription. There are no claim forms to fill out and no limit to the number of times you can use the card. These discounts are available only at over 60,000 participating pharmacies.
