If you’re living on Social Security, stretching every dollar is a must—and Costco is basically a goldmine if you know what to grab. Here’s what retirees should stock up on in July: 1) Prescription meds (the pharmacy deals are wild), 2) Kirkland Signature everything (seriously, from olive oil to paper towels), 3) Bulk pantry staples (think rice, pasta, canned goods), 4) Personal care in mega-packs, and 5) Health & wellness finds (multivitamins, first aid kits). Pro tip: Split bulk buys with friends or family to save even more! #Shopping #CostcoFinds #RetireeLife
