As one of its daily deals, That Daily Deal offers the Magic Mat Beach Mat for $12.49 with free shipping. That's tied with yesterday's expired mention and the lowest price we could find by $8. It measures 6.5-feet x 5-feet and features a "multi-weave technology" that allows sand to fall through it, ensuring that you don't sit on a sandy mat.

You can also buy three for $29.97 with free shipping, or $9.99 per mat. Both deals end today.
