We all love a bargain. There is nothing nicer than finding something you've been hankering after on sale. I'm the same, but increasingly I've become sceptical about the endless discounting the big retailers engage in. It doesn't feel fair when brands boost the price by 25% just to be able to offer a 20% markdown to unsuspecting customers. The two for one offers in supermarkets are fuelling waste and endangering the health of our children. We've become so conditioned to gravitate towards the sale item, we don't always appreciate the psychological manipulation involved.
