Last Year on the Green · July: Price per Hundred Grams

The idea: compare the price per hundred grams, not the price of the pack; then compare the price of what you will actually use.

The Honest Page

Which parts of this story are true, stretched or made up?

True

  • In shops, the unit price is the price for one unit of measure, such as per kilogram, per litre or per hundred grams. It is usually printed on the shelf tag below the product, next to the price of the whole pack. Source
  • Shrinkflation is when a product gets smaller while its price stays the same, so you pay more for each gram without the price on the pack changing. Source
  • In the case, £3.75 for 750 grams is 50p per 100 grams and £2.25 for 500 grams is 45p; 90p for 1kg is 9p and 55p for 500 grams is 11p; £1.50 for 250 grams is 60p, 90p for 120 grams is 75p, and £1.50 for the 120 grams actually eaten is £1.25. A pound for 300 grams of biscuits is about 33p per 100 grams; a pound for 250 grams is 40p.

Stretched

  • In the case, every shelf tag shows a clear unit price in the same unit. What we simplified: Real shelf tags sometimes use different units for similar things, such as per 100 grams on one and per kilogram on the next, or per item on a multipack. It is worth checking you are comparing the same unit before you decide.

Made up

  • The supermarket, its prices, Tara's £30 list, Juno, Mr Ahmed and Tara's mum's rule are made up. Unit prices and shrinkflation are real.
