If your Walmart sells the small 1.75 oz size of Millstone, then with the $2/1 coupon from the 2/13 RP insert, you should be able to get them for free. This is based on the price being $1.64, but check your local Walmart to see what the price is. The prices, I would think, should be pretty close to the same.
