If you have a smart phone, or a tablet, you're going to want to create a section for store apps.
Almost every store – grocery, home improvement, department, or craft/hobby stores have an app, which often contain very valuable electronic savings in the form of a coupon.
Depending on the coupon, you could save 25-50%, just for checking your app before you make a purchase!
I avoided a costly mistake when found myself in Joann Fabrics shopping for a specific craft product. I realized I had forgotten to tear out my coupons at home from the sales flier, and was all set to leave the store and come back later, when I had the idea to search for a Joann's app.
Sure enough, there it was, and with a 40% off coupon to boot. See? Quite a significant savings, and I never would have known had I not remembered to check for an app first!
