With a new 2-year data contract, Sprint offers the Samsung Galaxy Tab 3 16GB 7" Android Tablet in Pearl White for $49.99 with free shipping. That's tied with our November mention as the best price we've seen for any 16GB 7" Samsung Galaxy Tab. (It's also $216 under the lowest total price we could find for it without a data plan elsewhere.)
It features a 1.7GHz dual-core processor, 7" 1024x600 touchscreen LCD, 1.5GB RAM, 16GB internal memory, 802.11n wireless, 1.3-megapixel front-facing camera, 3-megapixel rear camera, microSD card slot, Bluetooth, access to Sprint's 4G LTE network, and Google Android 4.2 OS (Jelly Bean).
Frugal isn't smart if you put off replacing these things. Waiting too long can cost money or even endanger your health.
