It’s getting warmer and that means it’s flip-flops time! Okay, at least that’s what it means for me! And right now on Kmart.com, they have flip-flops marked down to 99¢. When you use the coupon code KMARTSAVE20 at the checkout, you will get 20% off all women’s and kids shoes, making them just 79¢! The only way this deal works though is if your local Kmart offers in-store pickup as the flip-flop are not available to be shipped.
