I'm Luke, and I built Deals of Opportunity because I just kept missing great sales on TTRPGs that I had on my OneBookshelf wishlists

Hey there, deal hunter! I'm Luke, and I created Deals of Opportunity because I wanted more out of my DriveThruRPG and Dungeon Master's Guild wishlists.

The whole OneBookshelf family of websites has such an awesome selection of titles of so many kinds. And they make it really easy to add lots of titles to multiple wishlists and keep track of all of the cool stuff you want to buy.

But then… nothing? You could share the wishlist to other people, and look through your lists. And that was it. Until now!

Deals of Opportunity lets you take all of those awesome wishlists and make them work for you. For any wishlists you add to your Deals of Opportunity account, you'll get notified when any titles on those lists go on sale.

And that's it, fully automated. To pull a line from one of my favorite 90's informercials, you just “set it and forget it.”

A simple way to never miss a sale on the titles you want again!

Frequently Asked Questions

Is it really free? What's the catch?

Totally free to use, and no catch! There are no plans to have any kind of premium service or paid tiers. Just sync your wishlists and get notifications of discounts. Links to titles are affiliate links, so any time you make a purchase through Deals of Opportunity, we'll get a small commission at no extra cost to you.

Can I only subscribe to one wishlist at a time?

Nope! Whether you have one wishlist or 100, you can add as many as you like to Deals of Opportunity. This is great for users who like to keep one wishlist per site, or break their wishlists into categories. Only add those you want notifications on to Deals of Opportnity, and you're set.

What does it mean to have a "preferred marketplace" set on my account?

The family of OneBookshelf sites (like DriveThruRPG, The Dungeon Master's Guild, DriveThru Fiction, Wargame Vault, etc) all share a common architecture, and in fact a common database. Your user account on one will allow you to log in to any of them. Your wishlists on one site are actually fully universal and can contain titles from any of their sites. You can actually open a title you find on DriveThruRPG on Pathfinder Infinite, or any other OBS site.

Choosing a "preferred marketplace" is just a quality of life feature for Deals of Opportunity users, as often we have sites we prefer. For example, I use DriveThruRPG most often, and would prefer to view titles there. This simply ensures any title links on the website or in your notificaiton emails open titles on a website you prefer.

You can change this selection at any time on the account settings page.

Can I choose to get notifications for certain format types or discount amounts only?

At the moment... no. But this is a feature that's planned for a release very soon! You'll be able to choose to get notifications only for digital or phyiscial titles (or both) and/or only when the discount exceeds a certain dollar value or percentage. We work closely with users on enhancing the app, so there are always new improvements rolling out!

Is Deals of Opportunity only for tabletop roleplaying games? Does it only work on DriveThruRPG and The Dungeon Master's Guild?

There are so much more than just TTRPG titles on the various OneBookshelf sites. You can bring your wishlists from Wargame Vault, Pathfinder Infinite, DriveThru Fiction, and all OneBookshelf sites to Deals of Opportunity and get notified any time they go on sale.

Will subscribing to or unsubscribing from my OneBookshelf lists impact them at all?

Nope! Deals of Opportunity syncs with your wishlists, but the sync is only one way. Adding or deleting your wishlists to your Deals of Opportunity wishlists will have no impact on the source data.

I see that some blog posts have wishlists I can subscribe to, will those impact my OneBookshelf lists?

Nope! These wishlists are built by us to allow folks to follow the great lists of titles shared in these blog posts, but adding them to your Deals of Opportunity subscriptions won't add them to your OneBookshelf lists. This keeps things nice and simple!
