Dunkin' Rewards members can collect 4X points on cold brew purchases on Monday, April 20, and get an extra 100 bonus points if they order ahead on the app, as National Cold Brew Day 2026 brings a wave of one-day coffee promotions.
The Dunkin' offer is part of Mobile Mondays, a push that rewards app orders on a day when several chains are leaning into cold brew discounts. Peet's Coffee is selling any size cold brew for $3, Scooter's Coffee is offering half-off cold brews of any size through its mobile app, and La Colombe is bundling a 12-pack of ready-to-drink lattes or cold brews, or any cold brew fridge packs, online for $25 instead of the regular $34 to $38.
For Dunkin', the deal is simple: buy cold brew on April 20, earn more points, and stack a bigger bonus by using the app ahead of time. The timing matters because National Cold Brew Day falls on a Monday, turning what would normally be a routine coffee run into a day built around app activity and quick discounts.
The offers also show how competitive the cold brew market has become. La Colombe Members get extra access to the online deal through Tuesday, April 21, while café customers can take $2 off any cold brew, half tan or draft latte at locations in New York City, Philadelphia, Washington, D.C., Austin, Chicago, Los Angeles and San Diego. Scooter's discount is limited to one per customer while supplies last.
That mix of rewards, limited-time pricing and app-only access leaves little mystery about the pitch: chains want the same thirsty customers, and they are using one day to press them into their own apps, stores and loyalty programs.
