Walmart offers the RCA 16GB 7.1" Quad-Core Android Tablet in Purple for $39.98. Opt for in-store pickup to dodge the $5.99 shipping charge. That's $20 off and tied with our mention from February as a very low price for a 16GB 7.1" quad-core Android tablet. It features a 7.1" 1024x600 touch display, 1.3GHz quad-core processor, 1GB RAM, 16GB storage, 1-megapixel front-facing camera, WiFi, Bluetooth 4.0, microSD slot, and Android 5.0 OS (Lollipop).
