For in-store pickup only, Walmart offers the Samsung Galaxy Core Prime 4G LTE Prepaid Smartphone for Cricket Wireless in White for $15.97. That's $64 off list and the lowest price we could find. (It's also the best outright price we've seen for this phone with any carrier.) It features a 1.2GHz quad-core processor, 4.5" 480x800 touchscreen, 5-megapixel camera, 2-megapixel front camera, 8GB internal memory, 802.11n wireless, Bluetooth 4.0, microSD slot, and Android 4.4 (KitKat).
