I've been frustrated with repeated delays in shipping my pre-order. Watching the website where these "by the end of the month" promises we're being made. Finally I saw the forum back up and learn some stores were stocked already. Jeez! Glad to learn that.
So although I ordered the $99 kit from RFDuino.com on October 24, I now have ordered from semiconductorstore.com and from Microcenter.com as well on January 3.
Microcenter sent me a shipment notice and fedex tracking number already.

RFDuino ? Bad business practices. Never sent me email describing delays directly. Gave incorrect dates on website. Or lost my order?
