Grubhub is running a month-long promotion throughout May that gives Grubhub+ members access to more than 10,000 deals across dozens of restaurant chains, including buy-one-get-one offers at Jersey Mike's, Sweetgreen, Buffalo Wild Wings, and Burger King, the company said.

The event, called Gold Days of Grubhub+, features more than $5 million in savings across weekly waves of deals covering breakfast, lunch, dinner, and groceries, according to the company. Through May 31, first-time Grubhub+ subscribers can lock in a rate of 99¢ a month for six months, which works out to a 90% reduction from the regular $9.99 monthly price.

The deals are structured by week. The first week, running May 1 through May 10, included a BOGO Personal Pan Pizza at Pizza Hut and a free three-piece Tender Combo at KFC, among others. Week two, May 11 through May 17, featured a free entrée at Chipotle $CMG +0.27% with a $20-or-more order and free McNuggets at McDonald's $MCD -0.67% with a $15-or-more order. Week three, running May 18 through May 24, offered a free Baconator at Wendy's $WEN +2.49% and BOGO wings at Buffalo Wild Wings, both requiring a minimum order.

Rounding out the promotion, deals available from May 25 through May 31 include a BOGO Turkey and Provolone Sub at Jersey Mike's on orders of $25 or more, a BOGO Royal Crispy Chicken Sandwich at Burger King on orders of $15 or more, and BOGO options on select Sweetgreen bowls on orders of $15 or more, the company said. A free classic or spicy chicken sandwich at Popeyes is also available that week with a $15-or-more order.
