Shopper has n8n read the weekly store flyer and ping them on price drops

THEIR CLAIM

a couple hundred dollars over time

TL;DR

What did u/Weary-Shame3170 use n8n for?

An n8n user built a 12-node workflow that checks their local grocery store's flyer PDF every week, pulls the price of their usual item, and alerts them when it drops below a set threshold. It still runs, and they estimate it has saved them money over time.

What they did

The workflow fetches the store's weekly flyer PDF, extracts the price of the brand they usually buy, compares it with their threshold, and sends them a ping when it's lower. They built it because the flyer updates at random times and they were checking it by hand.

How it went

It still runs, and they estimate it has saved them money over time.

"still runs, probably saved me a couple hundred bucks by now"

Worth knowing

  • They don't share the workflow or how often it checks. A commenter suggested a simple fetch-and-compare for spotting when the flyer changes.
  • Price check: n8n: no free plan; Starter: US$24/month, or US$20/month on a yearly plan (US$240/year) (checked Oct 26, 2026).

Try it yourself

Paste this into a chatbot, then add your own details underneath.

Here is this week's store flyer as text. Find every listing for [product or brand], give me the price and any deal terms exactly as written, and tell me whether it's below [my threshold]. If the item isn't in the flyer, say so.
