3 for 2. Check your receipt!

Buying in Clicks Clicks Table View Mall today. Taking advantage of their 3 for 2 offers with the little stickers (that has been their advertising slogan for years) BUT when got to till, queried my bill and was told one of the items is part of their Christmas campaign(only happening next week) so not yet available as 3 for 2 despite the stickers!!! SO WHY IS IT ON THE SHELVES YET? Or is it to fleece unsuspecting customers who might not notice it on their receipts!!!!!! Was told by Manager that item was not advertised as 3 for 2, but neither was the other item I bought and yet did get 3 for 2 for that. Absolutely disgusted and Manager not really interested! BE CAREFUL check your bill and not be duped. Guess where will NOT be buying Christmas gifts.
