People usually just go to the store they're used to going to, and it's rarely worth the effort of combing through card cashback, weekly coupons, CPG rebates.Most people leave real money on the table by not stacking them, and even more don't even know that these deals are out there....

so I built a way to automate it.You can use it for free, no login, currently NYC-only with ~690 stores.I built it so that you just search whatever you want (use commas if you want to search multiple items).
