In Canada, our grocery stores are so competitive on price that most of the actual bottom line profit derives from fining suppliers for all kinds of things (products not selling through, mislabelling, late shipments, short orders, back orders, lack of responsiveness, food safety infractions). Even the impulse items are only marginally if at all profitable. I only know this because we make financial software for the industry. It is a strange byproduct of competition.
