Grubhub will offer Rite Aid products for delivery on Gruhbub Marketplace. The companies announced the partnership with the drugstore chain spans 2,000 stores in 16 states. The Rite Aid deal marks Grubhub's first national drugstore partnership. The partnership builds on a similar deal with GoPuff announced last month. In a race for profitability and market share, major delivery companies have been entering new market verticals, adding marketing features and acquiring smaller competitors over the last couple of years.
