A day30p
A week£2.12
A month£9.09
A year£110.61

At one serving a day, this pack lasts 33 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

  • Servings: 264 ÷ 8 per serving = 33
  • In the pack: 33 × 1 serving = 33 servings
  • £10.00 ÷ 33 servings × 1 serving = 30.3p per serving
  • A week 30.3p × 7 = £2.12 · a month × 30 = £9.09 · a year × 365 = £110.61
  • Amount per serving: priced per serving — compare what each serving contains before choosing.
