Club Nintendo is celebrating the release of Dark Moon with a sale that will run for the next three days, appropriately titled "Luigi's 72 Hour Sale."
Not everything is Luigi-centric though, so be sure and check everything on the site before you ignore him (poor Luigi!).
On a related note, my Luigi's Mansion: Dark Moon review will be going up on Thursday, so be sure and tune in then to see what I thought. You can also catch the green goon later this year in his own version of New Super Mario Bros. U.
