333788057 (from March 24, 2010; post #40215) - 333478166 (from December; #40218) = 309,891
Assuming $40 average order: 309,891 x $40 = $12,395,640
The calculation makes a few assumptions:
1. The order numbers are sequential.
2. An average order is $40.
3. I know what I'm doing.
Of all the assumptions, #3 is the one most in question.
