I loved this week's sale on Purina One Cat Food. It was on sale for 2 for $4.00. There are $2.00 off one box coupons available - so I was able to stock up. I made a couple trips and did not clear the shelf until the last day of the sale. I still have coupons left so on the last day of the sale, I went and got a rain check to use with the rest of the coupons. You can't beat free!
