Saw this at Pac N Save Royal Oak. The bars are stacked opposite the checkouts. Not easily found at the shelves.
This has been $2 for a few weeks now in my local PNS, good snacks!
They must've vastly overordered or something, because they've been trying to move these at this price for some time now. It's funny, because that is a store that is perpetually out of stock of many things.
They also have the Tasti Indulge bars for $1.50 per pack. I tried both and these Peanut/Pretzel ones are a lot nicer.
