Want a hot deal on a Nexus 9... which will hopefully last longer than that nigh-inexistent one from HTC? Then head over to Amazon right now. One of the online dealer's "lightning deals" is fifty bucks off of the base 16GB model, bringing the total price down to $349.99. If you're an Amazon Prime subscriber, you can enjoy free shipping as well.
This is only for the black 16GB model - all others, including the white variant, are not discounted.
