Got some sort of attention:

Chris Farris II explains as follows:

We only had a limited supply they were priced so low because they were discontinued. Which means when we run out there will be no more available. When we changed that price we did not intend on selling them that fast due to the fact we did not send out anything informing anyone about this sale. We had no clue until Monday morning becuase we were not here. I apologize about this we are looking into this as we speak. I will keep everyone posted. Again I apologize about this inconvenience. This may explain where a lot of the orders came form.

FWIW,
