If you shop at a chain megacorp store, there’s probably like 10 layers of people you’d have to pass the info up to, which seems unlikely. Maybe better looking for customer feedback forms in person or online.
If you shop at a local independent, they either don’t do this sort of charity thing, or do it much more directly (as in the money doesn’t even flow through their own account) with a local charity or food bank, that sort of thing.
