3As....yes, fully booked. Called for 2 days and finally someone picked up the phone to tell me is fully booked. Asked them to put me on waiting list. As I know some of them will book, book, book then cancel after seeing the sample or unable to make it.
MWL has class voucher but is we need to accumulate purchase to earn it. Therefore, unlikely people can give you, maybe they can sell you at discounted price. I ever buy from someone at S$25 per class, total 3 classes in a card. It's valued at S$35.
I have 10% off for class.
