Head on over to the STP Facebook Page where you can print a nice $2 coupon which can be used on any of their products. If your Walmart has STP Gas Treatment priced at $1.97 you’ll be able to snag a bottle for FREE!
Here is your scenario:
STP Gas Treatment $1.97
-$2 off any one (1) STP Product
Please keep in mind that Walmart prices can vary between stores.
