I will buy 'Sum Wing', as can be purchased in Taste/Pakn'shop. $239 each can. Cheaper if buy in 'water product' shop, but I will only buy in big shops (like Taste or Sogo), as cannot guarantee if the 奶粉 is real or not if you buy in 'water product' shop.
2 of my friends' BB drink this 奶粉, they are fat and healthy.
