"Since all other outlets are announcing this even though it was not supposed to happen until August 1, yes, USB Block Erupters are having a price cut!
USB Block Erupters are now on sale at 0.60 BTC per device (free shipping to US). A huge number of units are en route, which will clear the backorder, and leave roughly 1,000 units available for next day shipping by August 1.
If you ordered an Erupter at 1 BTC, all is not lost yet. A coupon program is being initiated by ASICMINER and distributed by BTC Guild. 30% of the units sold at 1 BTC will be eligible to purchase a 2nd unit for 0.10 BTC (+0.05 Shipping/Handling). The exact method of coupon distribution will be announced when coupon units arrive, which should be around August 5th."
I've setup #15 at .55 btc: https://bitcointalksearch.org/topic/finished-15-asicminer-erupter-usb-55-btc-2000-shipping-263577
regarding .10, I will follow the expected coup distribution, per manufacturers parameters. Once it is available, those eligible will be notified with redeeming instructions.
