At Kmart, make a purchase of bed, bath, or home items worth $40 or more and get $40 in SYWR points. (Not a member? It's free to join.) Opt for in-store pickup where available to avoid shipping fees, which start at $6.99. (You can also spend $25 or more to qualify for free shipping, although some large home items require a $399 spend to bag free shipping.) That's the best general credit offer we've seen in Kmart in at least a year.
