Kmart offers the GreatCall Jitterbug Smart 4G Smartphone for Seniors for $100 with free shipping. (Amazon charges the same.) Plus, Shop Your Way Rewards members receive around $11 in SYWR Credit. (Not a member? It's free to join.) Assuming you'll use the credit, that's the lowest total price we could find by $61. Designed for seniors, it features a 1.1GHz quad-core processor, 5.5" 1280x720 touchscreen, 8GB internal storage, 5-megapixel rear-facing camera, 2-megapixel front-facing camera, 802.11 wireless, Bluetooth 4.0, dedicated 5Star emergency button, and a simplified operating system with large icons.

Of note, Shop Your Way Rewards members may be eligible for additional credits and discounts.
