Amazon tried but then ultimately stepped away from building its own cost-intensive Grubhub and DoorDash competitor in the U.S. back in 2019. Now three years on, it’s taking a different approach to tackling the space to build in one more sweetener to encourage more sign-ups to its Prime subscription service. Today, the e-commerce giant and Just Eat Takeaway — which owns Grubhub in the U.S. — announced a partnership in which Amazon will offer free membership to Grubhub+ for one year to Prime members in the country.

Grubhub+, when it launched in 2020, was described as the “Amazon Prime of food delivery”: like other loyalty programs run by other delivery services, it’s a subscription service where members get free delivery on orders and potentially other bonuses. It’s normally charged at $9.99 per month.
