You might look at this deal and think it sounds pretty mild. After all, the Nexus 10 is only $399 from Google Play. However, this deal can be had tax free outside of California and includes free standard US shipping.
This listing is for a new-in-box 16GB Nexus 10 just like you'd get from Google Play – WiFi-only, Android 4.2, Samsung Exynos 5 dual-core chip, amazing screen, and so on. Buying this tablet from Google will probably rack up taxes in the range of $30, and shipping is $13.99.
