Dollar General typically allows customers to use more than one coupon on a single purchase, but specific rules may apply depending on the type of coupons being used. For instance, digital coupons that are loaded to a Dollar General account can often be stacked with manufacturer coupons or paper coupons. It is important, however, to ensure that the coupons are valid for the items purchased and do not exceed the total purchase amount. Additionally, choices in promotions and discounts may vary based on the store location or specific events happening at that time. To learn more about coupon policies, customers might find it helpful to review the information available on the Dollar General website or refer to in-store signage that details current coupon usage guidelines.
