Poise Impressa Bladder Supports Sizing Kits are on sale for $6.99 at Walgreens. Plus, buy one and receive a $4.00 Register Reward. Print and use a $2.00 manufacturer coupon at checkout. The final price is $0.99!
Note: My store did not have the Register Reward promotion tagged, but you can find it advertised on page 10 of the weekly ad. The ads can be found in-store near the entrance.
