Stupid franchisee. I kept a coupon active for years after the promo ended for one guy. He liked his $11.99 Veggie lovers. The coupon was hidden, but if you manually typed the code, it worked. I called him personally after he complained to corporate about the promo ending. I walked him through how to get the deal and he ordered weekly until I sold the store. The new owners deactivated all old promos. He had my cell phone number, so I got to find out, after I sold the store, thst he now orders Papa John's.
