Since they are out of stock you could just email them and ask them. My guess is that you could probably do one per email address as long as you pretended the email addresses were different people, which means if they were actually different people then it should work to. I doubt they do more than copy and paste for shipping info so they may not even notice if you shipped several to the same address unless they happened to process the orders right in a row. On the other hand, when the next batch comes out they may raise the limit on how many you can buy and make this whole discussion less meaningful.
Emailed them two days ago. Still haven't gotten a response.
Thanks for your input though
use their skype, you will get a faster response, there is always someone supporting you there, as for your question, i find it strange what you said, i see that in the group buy there are people ordering 12 unit, which mean that you got a bad informations from someone, or just bad rumors
