Starbucks Thailand and JCB are offering a buy-one-get-one route for holders of eligible Thailand-issued KTC JCB cards on the 10th, 20th and 30th of July, August and September 2026. Buy any drink in any size and the free drink is a Tall, or 12-ounce, beverage of equal or lower value, capped at THB 160. The promotion begins at 8am on each eligible day and ends when the daily quota is used.
This is an in-store offer, not a delivery or mobile-order discount. Add the JCB Thailand LINE account, register the eligible card and open My Exclusive Deal followed by JCB Reward. Show the live code before paying with the KTC JCB card. The code lasts 15 minutes and screenshots are not accepted, so activate it only when the barista is ready.
Eligible Dates
The code is available only on 10, 20 and 30 July; 10, 20 and 30 August; and 10, 20 and 30 September 2026. KTC lists 2,381 privileges per promotional day. A date on the calendar does not guarantee stock, so an early visit is safer than planning a late-evening redemption.
Choose The Drinks
The paid beverage can be any size, while the free drink is Tall and cannot exceed THB 160. It must be equal to or cheaper than the paid drink. Alcoholic drinks, bottled beverages, ice-cream drinks and customisation charges are excluded. Ask staff to price unusual additions before the code is activated.
Redeem In Store
Mobile Order-ahead, Order to Table and delivery channels do not qualify. Present the live code before payment and use the eligible KTC JCB card for the remaining balance. The campaign allows one privilege per sales slip and one per LINE account per month, so sharing one account across several visits will not create extra entitlements.
Avoid A Failed Code
Confirm that the branch participates, the daily quota remains and both drinks meet the terms. Keep mobile data available and do not activate the code while travelling to the store. Once redemption is confirmed, the privilege is treated as used even if the order later changes, which makes the final counter check important.
Who Saves Most
The offer is strongest for two people ordering ordinary espresso, tea or blended drinks that fit under the free-drink cap. A solo visitor can still use it for two drinks, but should not over-order simply to chase the headline. Remember that the maximum gross value is THB 160 before any excluded additions.
