2) There's an offer on, which means everything else in the shop is more expensive to compensate for it. If I don't buy the item on offer my bill is actually larger than it would be, and if I do, it's the same price as it would of been anyway.
That's not right lol.
The market mechanism for shopping is quite simple.
Supermarkets are out to make a profit. They are willing to sacrifice profit on some brands for more purchasing power onto the others. Having Jaffa Cakes on offer will not cause increases in other food products to compensate. Can you imagine them changing the price every week because a different brand is on offer lol.
Oh and what you have been ON THE MAJORITY seeing is increases in prices for necessities. Supermarkets do not make major profit on necessities. It is often the necessities and their price and availability which bring customers to the store. Thus, they are the most competitive products between companies.
