I spent 3 years clipping coupons with an app and finally did the math, the Sunday paper still wins
I tracked all 47 coupon app offers I redeemed last year and they saved me $58 total, then my mom handed me her $2 Sunday paper with a Buy One Get One on the exact detergent I already buy and it beat the whole year's app savings in one clip, so now I want to know if anyone else has crunched their coupon app numbers and gotten a different result.
