the cheapest goods are sold as loss-leaders to attract high spenders to the biggest supermarkets on the outer peripheries of towns.
like konabunny, I just dont agree with this.
Supermarket margins are tiny, just a few percent.
The agressive market is primarily aimed at staple products to get ANYONE with any discretionary spending into the stores to try and sell higher margin goods to. Whilst this is to the benefit of everyone who enters the store (since nearly every household needs to buy the staples) it disproportionately favours those who spend less. It’s akin to the VAT environment where staple goods are exempt but “Luxuries” not.
As for utilities, Id certainly like to see household allowances based on targeting reduction in consumption. Set a feasible consumption threshold that lifts as many as possible out of fuel/water poverty, but after which the price ramps up quickly punishing excessive consumption.
