In anticipation of the upcoming solar eclipse, food and beverage chains across the U.S. are jumping on the bandwagon to offer discounts and specials to customers.

According to the Perryman Group, a Texas-based economic consultancy, the economic impact of the eclipse in the U.S. could reach an estimated $6 billion. Restaurants are certainly hoping to capitalize on this opportunity, catering to customers looking to partake in the festivities while saving a few bucks.

One chain getting in on the eclipse action is 7-Eleven, which is offering subscribers of their delivery service, 7NOW Gold Pass, the chance to order a whole pizza for just $3 on Monday. As an added bonus, customers can also claim a free pair of eclipse glasses, available while supplies last.
