You spent too much time thinking creatively on your own, and not enough time understanding how the world works. If you want to improve the world you have to understand it better. Go understand whether you can design a business process (involving your software) that's better than the ones they brick and mortar stores are using now, and then sell it to them (or "give it away for free" - or is it worth it to pay them?). THEN think about the implications.
