Metro, which is a Canadian grocery store. What happens is they get the coupons of all items listed as "special" automatically, and employees are supposed to throw away those without real discounts or even negative discounts.

I've seen things like "Special $5.99, used to be $4.99, instant rebate $-1.00".

It's their system which is junk. They print out stickers for every item listed in their fliers.
