There is a new $2 off any STP product when you like them on Facebook.
I checked at Target yesterday and items were priced between $2.49-2.99. You might find a better deal at Walmart or some auto supply stores- but .49 after coupon is a great deal!

These are priced at $1.99 at Advanced Auto Parts, and $2.42 for the fuel injected type. I bought 3 with no problems….
At Walmart, they start at $1.97.
