Same as the flyer krub. In shop they can try hot teas for free. That is a very strong promotion that no one in Thailand do before. 30% discount on "premium" organic English Breakfast is doing well, and Cake buffet will bring more people krub ;-)
There will be in shop promotion too. ;-)
Anyway, I will offer tea class for free which normally cost us around 500-600 baht per person krub. But this has to reserve because we limited the number krub. They will know how to blend teas, how to do the best hot tea and also learn what Sense Tea is actually for.
