I got an email reply and it seems that they are letting me use my preorder payment one one A4+ miner.  It's not certain because anything can happen between now and delivery. 

I gotta admit that this is pretty nice of them.  I have been reading about how buyers of the A5 had to pay full price on the customs and wondered how the hell am I going to actually make any money with these things?  The customs VAT seems to be about 20% of declared value to the USA. 

I also realize that this is a natural part of capitalism - people will extract as much as possible, as much as they can get away with.  When there's some guy in a back room figuring out that they can get an extra 30% and still have buyers clamoring for their miners then - well - forgidaboutit when it comes to magical profits. 

PS My main rigs are still 1060's.  Mining has taught me to be a tightwad.  "Ah, they work and they are paid for"
