Kmart offers the Smart Sense Donut Shop K-Cup 36-Pack in Medium Roast or Breakfast Blend Light Roast for $11.99. Plus, Shop Your Way Rewards members receive around $12 in SYWR Credit. (Not a member? It's free to join.) Opt for in-store pickup where available to avoid the $6.25 shipping fee. Assuming you'll use the credit, that's $12 off list and the best deal we could find. Deal ends January 28.
Note that the credit will be awarded one day after purchase and will then expire in 14 days. Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
