Jos. A. Bank offers two pairs of Jos. A Bank Split-Toe Cedar Shoe Trees for $20 with free shipping. (Add two pairs to your cart to see this price.) That's a savings of $30 and tied with the lowest price we've seen for two pairs. They're made in the USA and are available in sizes S to XL.
The internet has changed how we shop. But for many things, you're still better off buying the old-fashioned way.
