Well, this coupon doesn't say anything about excluding certain sizes and if you look at the shelf tag of this 10ct Gas-X product, you can clearly see that it's marked $2.44.
Take $2.44 X 3 = $7.32.
10 - 7.32 = $2.68 in OVERAGE for every 3 that you purchase. This is what is called a MONEY MAKER (MM)!
You can also use the coupon that was right above it for just $5/2 of the listed products. It's only $0.12 OVERAGE, but it's still a FREE product! :)
The coupon doesn't expire until 12/31 of this year, so don't feel like you have to rush out and purchase them right now or all at once. Please, do not purchase them simply to stand at the register and get paid, use the overage to cover the cost of something that you can't get a coupon for or that you have a coupon for but it's still not enough, like diapers.
P.S. This coupon was I believe only in the Des Moines Register SS. Or Star Tribune or Omaha Sunday paper, depending on your region. Those 3 are all super similar.
Just so you all know, the shelves will not be cleared out by me because I special ordered my own shipment of them through the pharmacy. :)
