It's a real scam for the stores. They take a 2$ commission on each transaction for a bag they already force to sell at 1/3 of the price. Therefore the commission is frequently above 50%!! PlUS they have an annual fee of 100$ they often don't even tell about upfront.. this app DOES NOT help your local stores, in fact they lose money using it.. the dishonesty about hiding the fees is a big turnoff.
