Well this is my 3th order, and this is the first time the order went wrong. :-(
Check the Txid on Blockr.io, I know Bitmain have been having problems with their payment api,
I have seen in other threads, that some people have been getting their ants even though their order shows as unpaid, unshipped, expired. I am kinda confident that they have the situation under control. Check the transaction

*Edit
I recived My order today, status is unpaid om bitmain siste.
My order from the 19th also arrive here today.
Did the site tell you the order had expired as well?
at first yes, but yesterday it changed to paid.
Thanks Biontic, and i check the txid, and I have 59 confirmations, so i'll sit and relax :-)
