When grocery shopping it can be taken for granted that you are paying the correct price for your household items. Unfortunately due to computer and man-made errors you can sometimes end up paying more than you bargained for. This is why it can pay to always check your shopping receipt before you leave the store.

Items scanned in twice
This has happened to me on a couple of occasions. I had purchased a tube of antiseptic cream worth around $10. When the total of my grocery bill came through at the register, I did think it seemed unusually high. On inspection of my receipt I discovered this item had been scanned through twice. I then took the docket to the service counter explained the problem and received a refund.
Here is another thing to watch out for. Supermarkets sometimes forget to remove their 'specials' tickets once a sale has ended. This can often be misleading and can cause you to buy an item you thought was on sale, only to discover later on your receipt you were charged a higher price. In this case you are entitled to a full refund and will get the product for free.
Here is a link with more information on the scanning code of practice.
