Updated Running totals:
5376 chips accounted for in 22 orders equals 244 chips per order. This number is probably skewed because people posting in this thread probably buy a higher than average number of chips.
10,000 chips = First 41 paid orders.
20,000 chips = First 82 paid orders.
Whelp, here's to hoping they had 20K on order

You bastards and your Big X's
I think they did order 20,000 chips. They may have been incorrect on some details, and made a couple mistakes, but so far have they have done the major things they said they would, pretty much on time too.
it makes sense to me that they placed two orders of 10,000 chip each. Perhaps their funds were originating from two different accounts, hence two orders. Or part of the funds were not available on May 10th so they placed as large of an order as they could to get those chips ASAP. When the rest of their funding came in, they could have made a second order.
