Free STP Product @ Walmart

 I have heard that STP Fuel Injector & STP Carburetor Treatment is selling for around $1.87 at Walmart (local prices may vary). Visit the STP facebook page, print this coupon for $2 off any STP product, and get it free and possibly overage. Expires 8/6/10.

If the price on this product is different at your Walmart please post it below. Or, let us know which STP product you purchased and got free/cheap with the coupon.
