I don’t believe in using a shopping list when I shop, but I always carry my coupons. You never know when there is a manager sale or clearance items allowing you to get something free or close to free when using a matching coupon. I cannot think of one brand that I am loyal to or wouldn’t get the comparable brand if it was on sale. Are there items that I spend more on? If a product makes an unwanted task easier, yes. When a new product comes on the market, there usually is a coupon making it affordable to try. For example, I tried the new Scrubbing Bubbles Automatic Toilet Bowl Cleaner that cleaned my toilet without me touching it. It was tremendous. You can join the Clean Toilet Club at www.cleanmytoilet.com/clean-toilet-club/ and receive a $5 coupon.
