I remember back in NYS going to a Giant Tiger when one first opened up in Potsdam. Those first few weeks, items had tags under them saying: EVERYDAY LOW PRICE. A few weeks later, the price jumped, but the tags remained. They'd even make up larger signs (~8.5x11) with the price of the week, still labeled the same. No matter what happened to the price of the week, up or down, they only ever referred to it by those 3 words.

The 3 P&C stores near me at the same time used to affix multiple stickers all over items with quite a range in the prices. There wouldn't always be labels of the shelf, either, and good luck finding a price check scanner. After a few trips, you'd figure out the lowest 2-3 were unlikely. They were also in the habit of leaving up sales signs for weeks after the sales ended. They would then refuse to honor the lower price saying: "You should have read the dates, it's not the store's fault the signs are still up." (Then.... whose fault was it? Employees are only responsible for putting them up, not taking them down? Can I have that job?) On the plus side, I got good at reading the dates after getting hosed enough times.
