Speaking of refurbs, the latest Nook Glowlight is now available as a refurb on B&N's website.
This is the 2017 model that is going to be replaced soon by the model that showed up on the FCC website last month, but it still presents a decent value (if you like the huge bezel, that is). This model was built by Netronix, and it has a color-changing frontlight over a 300ppi Carta E-ink screen. It also has 8GB storage, Wifi, and page turn buttons.
It is selling for $89, or $30 less than the retail price.
