Walmart continues to offer the Coolpad Rogue 4G No-Contract Android Smartphone for Walmart Family Mobile in Black for $19.88. Opt for in-store pickup to dodge the $4.97 shipping fee. That's $40 off list, tied with our mention from last week, and the lowest price we could find. It features a 4" 480x800 WVGA touchscreen, 1GHz quad-core processor, 1GB RAM, 4GB storage, 802.11ac wireless, Bluetooth 4.0, 0.3-megapixel front camera, 2-megapixel rear camera, and Android 5.0 OS (Lollipop).
