My complaint:
This supermarket advertises sale items online and in-store, but when they ring the item up, they try and charge you the regular price if you do not pay attention and when you bring it to their attention, they try and insist that it is not on sale until you show them but then they remove the sign with the advertisement on sale from the shelf. I have witnessed this several times and as a consumer, this is despicable.
Suggested solution:
I believe someone should visit this store and staff to this problem and apologize for trying to cheat consumers and charge them full price for sale priced items
