It pays to be a little older and wiser. On Tuesday, March 4, Walgreens agrees and is offering customers 55 and older a discount on most in-store purchases. (Proof of age may be required, so bring a photo ID. Plus, the offer is only valid with its Balance Rewards program.) On Senior Savings Day, you can save 20% on all Walgreens, W Brand and Nice! products…plus, get 15% off everything else, including sale items. Of course, there are some restrictions: Discounts are not valid on prescriptions, cigarettes, dairy products, liquor, liquor department items, phone cards, newspapers, magazines, stamps, gift cards, items or services submitted to insurance for reimbursement or where otherwise limited by law. Make sure to read the fine print on the bottom of Walgreens’ Senior Savings Day page for a full review of restrictions. If you don’t qualify, consider asking an older relative or friend to go shopping with you to get in on the savings. Be sure you’re a member of its FREE loyalty program, Balance Rewards, for maximum savings.
