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). Or - use the AI tool to help shop for you. If you're curious, it's powered by a trained LLama model.
Honest limitations are coverage and freshness. Id love some feedback on where the data looks wrong or is stale.
Question for the room - what to prioritize if you're working with messy, multi-source retail/pricing data? Is freshness or coverage the top priority if you cant get a uniform response from every source? curious on what to prioritize here.
