Deals of Opportunity

Deals of Opportunity knows that tabletop roleplaying game fans never want to miss out on a great sale on the titles they want, but don't want to have to manage yet another list on another website.

The problem is, the wishlists on DriveThruRPG and The Dungeon Master's Guild really don't do much at all besides serve as a shopping list.

This free tool lets users keep your wishlists where they are, updating them right from DriveThruRPG and The Dungeon Master's Guild, but be automatically notified when any titles on those lists are discounted.

Automatic, simple, and free.

Deals of Opportunity is such an underrated service!

Luke Miller is a writer, game designer, and software developer who lives in sunny California with his husband Roman and their two corgis, Luna and Sol. He has had a lifelong passion for fantasy and science fiction and has recently discovered a love for tabletop roleplaying games.

After exploring the world of TTRPG's as a player and game master, Luke was struck by the game design bug and quickly jumped into the creation of his first game: Journey. Through this process, he learned many lessons on what to do (and, more importantly, what not to do), and looks to take these learnings into the next game.

Now Journey is a Platinum bestseller and has been joined by a number of other creative tools and games, and Luke is excited to bring his passion for game design and software development together to create Deals of Opportunity.
