It is worth noting that some manufacturers may offer additional savings programs, such as loyalty rewards or discounts for purchasing in larger quantities. However, these programs typically have their own set of rules and restrictions.

When it comes to using coupons for prescription medications, it is important to be aware of any restrictions imposed by insurance providers or pharmacy benefit managers. These entities may limit the number of coupons that can be used within a specified time period, or they may exclude certain medications from coupon eligibility.
