Nothing fancy — just automated price checking so you don't have to do it manually
Prices Get Checked
A script runs daily and checks prices from the main UK protein retailers. Nothing clever, just automation doing the boring work.
Normalised Per 100g
Different pack sizes make manual comparison annoying. Everything gets converted to price per 100g so the comparison is actually fair.
You Pick the Cheapest
Filter by brand, type, or size. Sort by price per 100g. Buy the cheapest one. That's it.
That's basically it
It's a free tool I built for myself and thought others might find useful. No sign-up, no emails, no catch. Just check the prices and buy wherever is cheapest.
