I think what Zefir means is that only 15% of those who's chips have actually arrived, ie batches 1 & 2. Which is pretty poor really. (of course this doesn't incl you as you say you are in a later batch).
There may be some users who are waiting to pay S&H after they get their boards in hand from an assembler but my understanding is that S&H is when Zefir ships their batch of chips out. C'mon people...
Right, I always told to pay S&H only after you have your boards / chips in hand, to prevent refunding them in cases we now had. Therefore, the 15% were in relation to what has been shipped out - not to the total amount of orders. But it became better meanwhile, number is already at 30%+
It looks like all remaining chips will be delivered next week. Then I'll provide a list of payments due and hope to close this chapter soon.
Prepare your mining environment, miners (hint: especially getting the efficient PSU of your choice in time sometimes turns out to be difficult).
