This week Walmart has Pringles chips on sale for $1.47, Superstore has also price matched at $1.47 (limit of 4).
Checkout 51 has a $2 rebate when you buy 3 Pringles chips.
With the rebate, your Pringles will cost $.80 cents each!
Double check your PC Plus offers as well. I had an offer for 400 points on each Pringles I bought. Since Superstore already changed their price to match Walmart, I bought it there. Basically I paid $.40 cents for each Pringles chips!
