Pictures show four Nexus7 docking stations but the ad is broken down into 2 sets of two docks... with a discount for buying BOTH lots. If you only buy a single lot then you will only get two docks.These are New in (sealed) Box docking stations for the Nexus7 tablet. We are selling them in sets of two in case you want to have a docking station in two different locations rather than taking the dock with you to different locations.These came from a school district in Florida that apparently never opened them.See our other ads!
