Are the order numbers serial? They can't have received 2.6 mil orders, right? :O

The serials seem to have started at xxxxxxx23xxxxx. I'm not sure how serial they are after that, but that puts things on the high-end estimate at hundred of thousands, not millions.

They almost certainly aren't serial, for example, there seems to be a chunk of zeroes that are fixed removing at least a few digits.
