If you’ve ever tackled a do-it-yourself project of the crafty nature, you know the frustration. You are face to face with that edge punch, that set of artist’s brushes, that stem of artificial flowers, and the realization hits: You forgot your coupons. Michaels, Jo-Ann, and Hobby Lobby are champs about putting out weekly coupons for anywhere from 30% to 40% off a regularly-priced item. Occasionally, one of these national chains will up the ante to 50% off, and Michaels has dangled coupons of up to 25% off your entire purchase including sale items (but not clearance). So we’re talking serious bucks here — enough to make you put down the bird feeder kit and fly back home to get the paperwork. But now these stores have taken the coupon distribution one step closer to your purse with these FREE smartphone apps. Just whip out your phone and flash the coupon screen at your cashier for instant savings: Those stores all have apps you can use. Check our their individual websites for details.
