Pay less for the same things
Penny compares the prices on your own receipts: which of your shops is cheaper for what you buy, and which similar items cost less.
You bought semi-skimmed milk at two shops. It’s cheapest at Market Lane: £1.45 for 2 pints, 20p less than at Corner Shop.
Buy it at Market Lane and you save about £3 a month.
