Luckin Coffee is celebrating the end of May with a "Payday Best Day" promotion, offering 1-for-1 on every single coffee on the menu, from 25 to 31 May 2026. That's a full week to bring a friend, treat a colleague, or simply double up on your daily cup.
How to redeem
The promotion is redeemed entirely through the Luckin Coffee app. Simply open the app, select your coffee, and the 1-for-1 deal will be applied in-app at checkout. Product availability may vary by outlet, so check your nearest store on the app before heading down. Terms & conditions apply.
