You call it living paycheck to paycheck, they call it serving the people that keep them in business.
I used to work for eD and from the time HT subs were introduced there, there's almost always been some sort of backlog due to popularity, you can tell by looking in the eD thread here on AVS. There is a difference between living paycheck to paycheck and doing as much as possible in house without outsourcing.
I believe the one sub they do have in stock right now would exceed the limitations on the test anyway. And I'd be willing to bet anyone waiting for a different sub wouldn't want a free one going out before they had theirs in hand.
Now, I don't know if there was any conversation between Gene and eD with regard to this test, but that's just an example of serving your customers, the people that keep you in business.
