Scroogette goes grocery shopping

It pays to keep your wits about you in the grocery store. For instance, the bigger package doesn't always work out cheaper (like it used to) -

The 500g bag works out at £2.00 a kilo, but the 1000g bag has an "everyday low price" of £2.99 a kilo. Hmm...

And what about the profusion of flours? The upper shelf offers strong white bread flour - white very strong bread flour - super strong premium white bread flour (would that premium refer to price?).

Below, though, is own-brand "strong white flour" which will do just fine - at 60p for the bag.
