This week Walgreens has the Centrum vitamins at B1G1 50% off. Use the $4 coupons from 7/13 rp stacked with the $5/2 coupon in the July IVC for vitamins as low as 99¢ a bottle.  Obviously your best bet will be the Flavor Bursts and Centrum Silver because they are only about $10 to start with.  If you pick a more expensive vitamin (like Walgreens and Centrum hope you do), your mileage may vary.  Note that the Flavor Bursts bottles are 120, which only sounds like a lot – you take four a day, so it’s only a 30-day supply.
