Smokey,
Good idea. That's what I did, too. Cancelled the 'pre order' 3pack and just ordered two single units.
Not happy, though. They're shipping the units from Amazon (so they obviously HAVE units to ship), no problem, but they just won't ship the pre-orders at the special low pricing. I held up my end of the deal - "pre order before Nov 1 and get the 3 pack for $299 special price". But Securifi didn't hold up their end of the deal. On the face of it, it looks unethical - a classic bait and switch.
