How to save on Metformin
Metformin is a first-line generic for type 2 diabetes. It’s usually inexpensive, but ER vs IR and strength still matter for price and tolerability.
Mail order vs your pharmacy (savings angle)
Standard tablets don’t need cold shipping—mail-order 90-day fills usually compete well on **total** cost vs local once you add your time and gas. Urgent new starts: local may be worth a higher per-fill price.
