I had to go to Microcenter today for a tool as I was helping a friend fix a coffee maker. I checked before I went and they said they were out of both the rPi 2 and the rPi zero. I found a whole display of the rPi2 and snagged one, in fact, they were on sale for $30! No luck on the rPi zero. I'll be up that way again next weekend, maybe I'll swing by and they'll have the zeros.
I spoke to a few sales people about them and they said both units don't stay in stock. They get 100 in and they are gone in a couple of days. You'd think they would order larger quantities or more often.
Looking forward to getting the rPi 2 up. I need to learn how to program the flash card from a PC. I guess if I had a USB card reader I could program it from my rPi B. I think have seen instructions on how to do that as well.
