In his bulk order thread for 500+ USB asic miners canary is selling them for .305 BTC each in his thread here
https://bitcointalk.org/index.php?topic=276441.0 Unfortunately I can't exactly afford to drop a total of 152.5 bitcoins but I do purchase about 25-30 at a time.
I do see this group buy only going well for users purchasing more then 25+ currently if you buy 25 miners at his current cost of .33 per each miner at 25 miners your spending 8.25 bitcoins + roughly $11 in shipping for domestic priority flat rate medium box.
If this group buy is setup I wont be able to pay the extra costs for shipping so that will have to be covered by you but at .305 per miner at 25 miners your spending 7.625 bitcoins so you would be saving 0.625 bitcoins on a 25 miner order which is roughly $70 USD in savings not including the shipping costs.
If I see that people are interested I will update this thread into my first group buy, and offer the same service where you can buy your own shipping label with USD and then email the pdf label to me and also offer to add the costs of shipping into your bitcoin order as well since this really would only save for higher orders it will be medium flat rate boxes which fits up to a 100 usb asic miners and the large flat rate box which can fit up to 140.
