We have a new coupon for STP and the cheapest place we could find to use it was Walmart. The Target stores in our area do not carry it. You may have better luck where you live.
The Twin pack STP gas treatment packs are priced at $3.94, so just $2.24 after coupon. As you can see the single bottles are $1.97 so a much better value to buy the twin pack.
STP Gas Treatment Twin Pack $3.24
