Get a K-Mini Plus Single-Serve Coffee Maker, normally $99, for free at Keurig.com when you enroll in a 12-month K-Cup subscription. Enrolling in a subscription also provides 25% off on K-Cups and free shipping on subscription orders. We can't find another K-Cup subscription service offering a discount and free machine. In order to avoid being charged for the coffee maker, you must order a minimum of 24 boxes of 20,- 22-, or 24-count K-Cups or 24 bags of coffee to be delivered over six orders with a minimum of four boxes or bags per order. You can create your own custom subscription or choose a curated selection. For example, you can subscribe to the Green Mountain Collection. It includes four varieties of 24-count K-Cup boxes, normally $14.99 each, but you would get them for $11.24 each. These K-Cups typically sell for $12-$15 per box elsewhere online. All in all, your first order, which would contain 96 K-cups, would cost $44.96. Sales tax is charged in most states.
