Pamida Double Coupons

After we got groceries, we went to Pamida because it was double coupon week. I got all the items pictured below for $8.14. The full retail price at Pamida would have been $38.39, for a savings of $30.25, or 78%.

Lays chips were $2.50-$1 coupon doubled to $2=$0.50 each
Dial soap was $4.50-$0.35 coupon doubled to $0.70=$3.80
Tampax tampons were $2.49-$1 coupon doubled to $2=$0.49Always pads were $2.49-$1 coupon doubled to $2=$0.49
Halls were $2.29-$1 coupon doubled to $2=$0.29 each
Herbal Essences shampoo/conditioner was $2.50-$1 coupon doubled=$0.50
Kiwi shoe laces ranged in price from $1.29-$1.99, used $1 coupons doubled to $2=All FREE
Coke ($1.25) and Reese's ($0.89), used $1 when you buy both coupon doubled to $2=$0.07 for each, or $0.28 for all 4.

I also bought Mega Packs of Luvs diapers that were on sale for $8.99, used $1 coupons that doubled to $2.00=$6.99 each, which is less than the smaller packs sell for.

The Coke/Reese's coupon confused the cashier as it only double up to $1.25 (I think because it attached to the Coke, and they don't give overage on double coupons). Eventually she doubled it manually, put away the coupons she had rung in, and gave me my total. However, I was fairly sure she hadn't rung in all my coupons--there were even two separate piles, one she had already rung in and one she hadn't, so I asked her if she had rung them all and she said yes. So I paid and then when I had my receipt, I counted up the coupons on the receipt (14) vs. how many I had given her (19). She was still trying to figure out the Coke coupon with a co-worker, so I said I was sorry to bother her, but explained how not all the coupons had been rung in.
Then the two cashiers went back and forth about the best way to handle the situation. She pulled out my coupons, I pointed out the ones that hadn't been rung in, and one decided they would need to void my original purchases and re-ring everything. The other one didn't want to do that, but then the drawer would be short. I apologized for the trouble, but I knew I was right. In the end, she gave me cash back for the five coupons without re-ringing everything and was going to leave a note for whoever reconciles the cash drawers. It was $8.20 back, so definitely worth my time to make it right. Then Raina, Ollie and I spent the $8 for hot dogs and treats at Dairy Queen!
