At Kmart, buy one pair of men's, women's, or kids' shoes and get a second pair for $1. Plus, all orders receive free shipping. That beats our September mention (which required a minimum spend of $49 to get free shipping) and is the best multi-buy deal we've seen on shoes from Kmart. (It's a rare no-minimum free shipping offer, saving at least an extra $6 on most orders under $49.)

Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
