If you did not noticed, I got Block Erupter USBs for 0.1 BTC as compensation for my early buyers. I am still waiting Friedcat confirm he will ship the remaining quantity promised (70% of the original pre-orders). Moreover, I am quite convinced that Block Erupter USB sales are not going to keep it up for 0.89 BTC each. This price is out of question when compared with other devices being released by trustworthy ASIC vendors. If Friedcat or even you want to keep the sales flowing to clear the stocks, you will have to decrease the price to a very low threshold.
