As one of its daily deals, That Daily Deal offers this Unisex The Life Aquatic Inspired Team Zissou T-Shirt in Blue for $9.99 with free shipping. That's $5 under the lowest total price we could find for a similar T-shirt elsewhere. It measures S to XL. (Sizes XXL and 3XL are available for an additional $1.89 and $2.49, respectively.)
Of note, it's also available as a 4" x 6" vinyl decal for $3.99 with free shipping. Both deals end February 11.
