@CryptX, by my calculations the retail cost of an 86MH A2 miner from Innosilicon is around US$0.12 per KH of mining power for purchases of 10 or more units (admittedly without freight).  However, the Scrypt-X share pricing above works out to a price per KH of ~US$0.16 (at US$420/BTC), or a 33% premium.  What is the reasoning behind this difference in price?
