If you were hoping to gift your groomsmen with something that’s out-of-this-world unique, we found it (literally)! Though lots of companies claim to have the right to sell you property in outer space, the gang over at Lunar Land boasts being the only one legally allowed to do so. Purchase an authentic acre of land on Mars for the guys, which I'm guessing they'll be proud to claim, or even name, once you do. To make bragging easier for them, the standard gift package comes with a deed that lists the actual quadrant, plot number, and location of the purchase. Plus, true sci-fi geeks will go nuts over the futuristic Mars-themed envelopes and packaging.
