£32.99 for 900 g at Myprotein. That works out at £1.31 per 25 g protein, which ranks it 79th of the 160 whey protein concentrate products we price across 8 UK retailers.

How we worked it out
- Servings: 900 ÷ 30 per serving = 30
- In the pack: 30 × 21 g = 630 g
- £32.99 ÷ 630 g × 25 g = £1.31 per 25 g protein
- A week £1.31 × 7 = £9.16 · a month × 30 = £39.27 · a year × 365 = £477.83
