I built this because I see that grocery savings are achievable in NYC. 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). 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.

Could you build this?
Partial The web application interface and shopping basket optimizer are easy to vibe code, but scraping and normalizing weekly circulars and dynamic pricing across 690+ independent grocery stores requires continuous data engineering.
What it would actually take: The backend needs robust ETL scrapers (handling platforms like Flipp, Instacart, and fragmented independent bodega/supermarket flyers via OCR/vision models) running on daily/weekly schedules with schema normalization for SKU matching. Maintaining reliable scrapers against varying flyer layouts across hundreds of stores requires ongoing data maintenance and automated parsing pipelines.
