The 2013 Nexus 7 is eligible, of course. Apply the coupon coupon code 24373 to take the price down to a mere $179 for the 16GB and $219 for the 32GB. This also works with the 32GB Nexus 10 ($429 to $379) and the Samsung Galaxy Note 8.0 ($359 to $309). There are a few other tablets to consider, but Staples doesn't have the most expansive selection. Still, there's some good stuff.
All these devices should include free shipping, but you're probably going to be stuck paying sales tax.
