One of the great deals for these coupons will be at Walgreens. A coupon for Finish Quantum Powerball Tabs or Gelpacs will be in the Smartsource.
Walgreens has it on sale for $3.49 and you will get a $1 RR back for it.
$3.49-$2.50 coupon = 99¢ OOP and get back $1 RR.
Use multiple coupons to get more than one and ring each box alone. Don’t pay with the RR you just got or chances are you will not get one back.
