Starting today, there's a Kinohimitsu promotion going on in Qoo10 - Just log onto Qoo10 and search for Kinohimitsu, and you'll find the various products!
My personal favourite is the Smooth'D Cleanse & Shape (The yellow packet one), because it tastes of passionfruit. It's a cleanse drink, which helps with detoxing, but definitely not the diarrhea inducing type of cleanse drinks. xD
Kinohimitsu is thus far the only brand which seems to ensure that their products taste good across all the board, so it makes the apprehension of trying out new products much lesser.
If you manage to get the products at the promotional price, just grab it :) You won't regret.
