Right now, there is a coupon for $2.00/1 STP Product on the STP Facebook page (you will need to like them first).  It has been repored that the STP Fuel Injector & Carburetor Treatment is priced at $1.87 and STP Gas Treatment products are priced at $1.77 at Walmart.  Use this coupon and you could get them for FREE.  WOW!

Thanks Eric!
