Why Not Just Use Another Comparison Site
Cluttered pages built for ad space, not for finding a price fast.
One clean table. Price per 25g protein, front and centre.
No easy way to line products up side by side across retailers.
Every product ranked and filterable in one live table, side by side.
Prices can sit unchanged for weeks after retailers move them.
Pulled from UK retailer feeds on a rolling basis, not a static snapshot.
Ranks by sticker price, so a small tub can look cheaper than it is.
Ranks by price per 25g protein, so pack size never lies to you.
