In the time it took me to finish up that post, Amazon appears to have sold the last of their FOC Gen2 Combaticons. It wasn't noted as being limited stock either like they do when items get to less than 20 in stock... so I'm guessing a scalper may have snapped them up at that ridiculously cheap price to easily resell at double that price (they go for about $80-100 on ebay at the moment).
I've left the link up in case they get some more in stock, or an order is cancelled.
