This - the dirty secret of most rebates and coupons is that without them customers don’t buy the product as much. But then for those who don’t have the discount still but for the increased price.

THEN most charities offered are in affiliating with the offering corp. Meaning they get tax write offs and a portion of the donation through their offering. The donation is made in the business name, not yours.

If you don’t return it or discount, they pocket it.
