What organization regulates coupons?

Coupons are primarily regulated by the Federal Trade Commission (FTC) in the United States, which oversees advertising practices to ensure they are truthful and not misleading. Additionally, the U.S. Postal Service (USPS) regulates the distribution of certain types of coupons, especially those sent through the mail. Individual retailers and manufacturers also establish their own terms and conditions for coupon usage, which must comply with federal regulations.
