What do you do just before you decide to upgrade your old device with some new hotness? You sell the old stuff on eBay, right? Well, B&N doesn’t seem to have any better ideas than you as it’s started offering its classic Nook e-reader for $99 on the online auction site, undercutting its own price by $50 . This is the WiFi-only dual-screen unit, as you might surmise, not the Color tablet that’s been treading dangerously close to being a fully fledged Android slate. If you’re an E Ink loyalist on a budget, this might just be the opportunity you’ve been waiting for, though don’t blame us if Barnes & Noble comes up with a fancier, more lustworthy model in the time it takes for that free delivery to reach your door.
