Expansys offers a number of bundles including the Nexus 4 and Nexus 7 as part of their Black Friday deals. A standout is the 16GB Nexus 7 + 8GB Nexus 4 refurb for $159.99 shipped. Double the storage on the Nexus 4 to $16GB for $20 more at $179.99 shipped.
These are both 1+ generation old machines but as Google’s flagship Nexus devices they are fully upgradable to the latest Android 5.0 Lollipop. More at Expansys USA.
