Macy's has the bestselling 10-piece Cuisinart coated knife set marked down to just $13.93. This is regularly $40, so you're saving a whopping 65%. Since this item is on clearance, no promo codes are needed. That also means that it can sell out at any time. So if you want it, then I suggest ordering sooner rather than later.
Make sure to sign up to become a Macy's Star Rewards Member so you can get them shipped with a lower $25 threshold. You usually have to spend $49 or more for free shipping, so signing up saves you money.
