Google wants to entice you to buy a Nexus 7 from the Play Store, but at the end of the day, it doesn't matter where you pick one up. So if you're looking to snag one in time for Christmas at a discounted price, Office Depot is currently willing to sell you one for $50 off. This brings the price of the 16GB model down to $179.99.
If you insist on buying the larger 32GB model (and really, I wouldn't blame you), Office Depot is willing to part with that for $40 off the usual retail price. It's not as large a savings, but hey, $229.99 is what you would usually pay for the 16GB model, so it's still a good deal.
Interesting enough, this deal brings the 16GB 2013 Nexus 7 down to the same price as last year's version. If for whatever reason you still prefer the original, you can pick that up for the same $179.99. I wouldn't, but I'm well aware that the world doesn't revolve around me.
