Pamida Double Coupons

Pamida had double coupons again this week, and since I had to get some groceries for Jackson's birthday party, I stopped. Some coupons doubled for more than their original price, so the overage went toward other things:
Suave deoderant--$1.29-$.075 coupon doubled=$0.21 overage
No Nonsense nylons--$0.67 on clearance-$1.00 coupon doubled=$1.33 overage
(They aren't even my size, and I really don't wear nylons, but I can either donate them or sell them at a garage sale, if Pamida is going to pay me to take them!)
Trident gum--$1.19-$.075 coupon doubled=$0.31 overage
Vitamin water--$1.39-$1.00 coupon doubled=$0.61 overage.
I also bought two SoBe Lifewaters at $1.49/$1.59 and used 2 $0.50 coupons, making them $0.49/$0.59 each, and a tub of Pampers wipes for $4.19!!!-$1.00 coupon doubled=$2.19.
All of the above, plus 12 $0.99 packs of cards for Jackson's birthday party, and a couple of game prizes, totaled $17.62.

I only saved 28% at Super One this week because I had some specific things I needed (not on sale, had no coupon) for the party. I also spaced out on a couple of coupons I could have used. I did remember to get back the $5 I was overcharged last time when the cashier rang two boxes of cereal twice.
