Kmart discounts a selection of Smart Sense products, with deals starting from 33 cents. Plus, Shop Your Way Rewards members can spend $10 or more to get 100% back in SYWR Points. (Not a member? It's free to join.) That's tied with last week's mention and assuming you'll use the credit, makes each of these items completely free. Opt for in-store pickup where available to avoid shipping fees, which start at $6.99. (You can also spend $49 or more to qualify for free shipping, although some items are available only via pickup.) Choose from snacks, medicine, cleaning supplies, and more.

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