Memory Foam Slippers under $10

I am a huge fan of slippers, especially since it is cold here in Illinois about six months of the year! However, I HATE spending money on them. Macy's has these Memory Foam Slippers on sale today only for $8.76, reg $29.99! I realize they aren't the cutest things in the world, but they have great reviews for comfort, warmth and they are super easy to slip right on. Free shipping offered for any order over $50 and free in-store returns.
