N2A Cards (R) - Transform your Nook Color into a Kit-Kat 4.4.2 Android Tablet (new 2014 version) - (8 GB)
I actually purchased the wrong card (bought the Nook Tab card instead of Nook Color card).  I didn't realize it so I created a service ticket on the N2A site.  They emailed me back within 20 minutes, told me I bought the wrong card, mailed me the right one (free of charge) along with a pre-paid return envelope for the wrong one.  Who else will do this for you...can't think of many that would.
