Shaw's review: pricing

This morning I went into shaws as I do quite a bit. There was a sale tag on the family size smart food popcorn for 3.99, reg 5.29, there was also items that were marked the same sale price, all but the cheetos, puff. One of my complaints is that why is all the party/family size on sale for 3.99 and not the cheetos, puff. My other complaint is that I brought one of the family/party size smartfood popcorn to the cashier, thinking it was going to ring as 3.99 and it still rang up at 5.29, even after my loyalty phone number was entered. I didn't have to time to have a manager go look at the sale and then give me the sale price. One resolution that I would like is to buy the family/party size bags of cheetos, puff as 3.99 and the smartfood popcorn as 3.99.
If I wasn't watching, I would have bought the smartfood at 5.29, not the sale price. I have noticed a few things like that. So can you imagine if I wasn't watching my receipt, how many times I would pay full price instead of the sale price. How would you like to happen to you.
I would like a response to this problem.
Thank you
