Eshop-Best via eBay offers this 8GB 7" Android Tablet for $42.99 with free shipping. That's $20 off and the least expensive new 7" 8GB tablet we've ever seen. It features a 7" 1024x600 touchscreen display, ARM Cortex A9 1.2GHz dual-core processor, 512MB RAM, 8GB internal memory, 802.11n wireless, and Android 4.2 OS (Jelly Bean).
There's a less expensive way, and then there's the way that works for you. The two may not be the same.
