Anyone know of any errors supermarket price? Or is it a trick?
For example, there are some new (expensive) Cadbury Roses Chocolates luxury boxes, you may have seen them. They are selling around the world for almost five dollars. In our local Morrisons very recently ISH only € 2.50 () for a week or and (Lucky me, a lover of chocolate!) and bought a couple of boxes …. so, why not? Anyone else any experience of this? Seems to have realized and the price has returned to extortion … Is it just a marketing ploy?
Marketing trick! is just to get hooked on a product
