Space may be the final frontier, but the exorbitant shuttle fees would crash your budget. Instead, blast into the water with today's deal from Brownie's Yachtdiver Stores: Pay $99 (regularly $299) for a day-long PADI Discover scuba diving course, featuring a classroom and pool session. All dive gear is included, and with classes limited to just six participants, it's never been easier to get your feet wet. Or pay $299 (regularly $599) for a PADI open-water certificate course, with four open-water dives. Take the plunge at the West Palm or two Fort Lauderdale locations, where you'll learn the ins and outs of your equipment during a classroom lesson; test out your skills in the pool; and finally make a series of four open-water dives. This is a great way to begin your stellar journey under the sea.
