I'm a Brisbane dad in a single-income household with two young kids. Like most families, we're always looking for ways to stretch the weekly grocery budget without having to compromise on what goes in the trolley.

For a while, my "system" was a note on my phone — a list of URLs for products at Coles and Woolworths — and every Wednesday I'd sit down and manually check each one. It worked, but it was tedious. I'm also a data nerd at heart and started getting curious: how often do products actually go on sale? Is there a pattern? Are some things never worth buying at full price?

So I built dropr for myself. I vibe-coded the whole thing from my notes and my Wednesday workflow, mostly during late nights after the kids went to bed or during my commute into the city. It does exactly what I needed — nothing more, nothing less.

Now I'm putting it out there in case other families find it just as useful.
