Differences between 699 is and original price of 470 is probably distributor's margin mostly.
Those who think they will get their boards before early November, I suggest to think twice.
To those wanting to support burnin, you guys could always donate.
I am out and deleting my vote as conditions were changed.
I waited for long to buy a product from burnin and now seeing what was done, I can just feel sorry for the energy, time, effort and money of all people involved (including myself).
@burnin,
I do appreciate your work and effort, and if I may say; you shouldn't allow this to happen.
If distributor is to be blamed, get rid of them and do business with someone having more realistic view on market and with one willing to work with less margin.
If you can't find anyone, do it yourself or you will loose all these people waiting for your boards.
I am speaking this as a friend, and this is just a hobby for me to support network and get involved. Having said that and, I don't want to overpay what ever product I am buying and this one is too expensive for me and probably bad investment with price set way too high.
You said it better than me

Same boat here!

If the deal was exclusive, burnin has handed a monopoly to Cryptx and asic-hardware.com. Cryptx already has his orderbooks from the bitburner - with the correct pricing this would have been a win-win-win for manufacturer-distributor-customer.
I hope this wasn't an exclusive deal and burnin may consider allowing the free market to dictate distributor pricing by stating minimum orders and terms of business for new distributorships. Group buy anyone? TBH unless anyone has volumes of Bitfury chips about to be shipped, it's almost academic and the monopoly will both prevail and likely fail (if that's even possible!), dragging burnin's reputation down with it.
