I apologize backorders have never been fully eliminated, it's just difficult to guess when big orders will hit. I'm hopeful that the number of units currently ordered will all arrive during next week (I know at least 300 on Monday, 500 more Mon/Tues, 500 unknown date), which can finally get the store caught up. Of course, there's no telling how many orders will hit as a result of the price cut, but hopefully the 800 extra units on order provide a decent buffer.
It's unlikely that any first day orders will receive coupons. I'm only given coupons for 30% of the total orders that were sold at 1.05 BTC.
