I sent them an email requesting the total price to Canada, and in their reply they commented "Because now is near the Chinese Spring Festival,and now we have too much order need to finished them until 28th Jan,so that if you pre-order now,we need to shipping out to you after 15th Feb,do you mind it?". Bit Engrish-y, but yeah, sounds like orders now will be shipping out in February.
I was told that if you pre-order now and the unit ships after Feb 15th, then you get the 5% discount. It doesn't start apply right now. Here's hoping it ships earlier than later.
You save $10 if you can wait a month's time. Either way, they have stopped taking orders as of yesterday so all orders for the NFB-12 will be considered pre-orders.
