Don't do it, Johnny! Merric's advice will lead only to disaster!
Because, you see, by the time you and your players are done with your "buy, grab, sink" cycle, Wizards will have sold so many copies of UA that they'll release three sequels! Then your players will really have kewl options to pester you about!
Plus, you'll be arrested for dumping boxes full of books in the ocean, where they will inevitably bonk some poor endangered aquatic critter on its head (or head substitute)! The next thing you know, someone will be parking the Rainbow Warrior in your front yard!
And people will overuse exclamation points! See?!!
