Why do companies print coupons with "do not Double" when the stores are the ones who cover the cost of dbling?

Question

I see coupons, especially the ones dispensed on store shelves, which say "Do not double". Since the stores themselves are absorbing the cost of the doubling, why should the manufacturers care?

Answer 1

A little inside info. The grocery stores send all coupons to companies who pay them per pound for the coupons. That company then sends the coupons back to the manufature to get thier money. Also, sometimes that product is a product where there is very little mark up so to double the coupon would make the stores profit smaller.
