I purchased some food in the small food shop beside the IKEA checkouts. The items were priced but when I had gone through the checkout I noticed that I was charged the display price but I was also then charged a 13.5% tax on some of the food items purchased (cinnamon cakes). I was under the impression that where an item is priced on in the display area then that is the price you should be charged at the checkout? Am I right or wrong on this?
