Zefir has received refunds from Avalon for 30,000 chips.
Also Avalon is supposed to be shipping large numbers of chips starting Wednesday.
If this is the case then said chip substitutions will happen -- batches 3,4,5 replacing batches 6,7,8.
I assume this is why Zefir extended his refund deadline.
Edit:
Chips for order #2 are now refunded. It is still for sale but without the chips.
Suggested opening bid reduced accordingly from 15.89 to 8.71 BTC
