Update: Kmart will one double your first like coupon per item, so this may or may not work for you. If you purchase one case, it would be $1 for the 12 pack.
If you were able to print enough of the $1/1 Pepsi coupons when they were available you can snag a great deal at Kmart beginning Sunday.
Kmart will be doubling your first 5 coupons with a $25 minimum in grocery, beauty or health items purchase. You could do the following:
Buy (4) Pepsi 12 packs $2.50 ea
Use (4) of any of the printables here (no longer available)
= $0.50 for each 12 pack!
You could also consider price matching at Walmart and snagging them for only $1.50 ea which is still a great price!
I will have Kmart deals for next week up soon!
