Price rang up at till not the promotion price

Beware of pricing ****s at Checkers Allansnek. They advertise Black Friday weekend specials in pamplets and in store on the shelfs, however at the tills they ring up the full price not the discounted price. This is an old trick of theirs as it happened to me several times before. This is very dishonest from a large supermarket chain. Again I was overcharged today and only noticed when I got home. Stay away from that store or check every item on your till receipt before leaving the store. Ill avoid that store in future.
