There is a new coupon for STP products that will save you $1 off one STP product, but you have to watch a mega short video first. I just watched it and it is approx. 10 seconds long.
STP fuel injector cleaner is priced around $1.90 at Walmart, so with the $1 coupon it would be less than a buck!
I saw it at 99207 zip as well as 12345. The coupons have a Walmart logo on them, but that is advertising only. They are manufacturer’s coupons, accepted at any store.
Thanks Become a Coupon Queen
