Hi,
I know this is old but this may be useful for someone. My daughter has been on Neocate since she was 3 months old (she will be three next month). We first got Neocate from Jacobson at extortionate rates. So if you can, see if you can get friends/family from the US to send over.
We normally order 24 tins of Neocate (she's on Junior now) which, including shipping, costs us about HK$7,000. 24 tins from Jacobson would cost you about HK$10,000.
The only thing is your friends/family needs to have a friendly doctor who will write the initial prescription. Once you are in the Neocate system it's just a question of reordering.
Hope this helps someone. Useful to know if you're going to be using Neocate long term like us.
