Update 8/18/14: The deal that quickly sold out last time is back.
A 16GB Nexus 7 might leave you tight on space, especially if you plan on playing multiple games on it, but at $129.99 this restriction can be overlooked. The tablet is again available at this remarkable price on eBay Daily Deals, and while it's a refurbished model, beggars can't be choosers when we're talking $100 off.
To make the tablet even more affordable, shipping is free. A replacement is rumored to launch later this year, but until then, this is a good chance to run what is still one of the best Android slates out there without breaking the bank. Besides, it's not like the device is going to stop functioning as soon as the next one arrives. The 2013 Nexus 7 still has some life in it yet.
