I use the app for Hobby Lobby, Michaels, and Joann's. Also I use Red Laser app at Walmart. It compares the price off any barcode to find the lowest price of it sold and then Walmart will give me that price. I have saved enough to pay for the Iphone. Don't miss out on savings by not utilizing technology. And stay current with what apps are available per store. All the national stores have one. If you go to the store site on your smart phone the app will appear if you don't have it. You can download and install it in about a minute. All store apps are free. I used the same phone coupon at Hobby Lobby for four items at one check out. If you have the paper coupon you need one coupon per item.
