Website with Steam wishlist

ITAD is more powerful than most people realize. The most obvious features beyond a Steam wishlist are that it can also:

• Check for prices at stores other than Steam itself.
• Check for prices on non-Steam versions of a game (such as games on GOG - you can filter it to watch for only Steam DRM).
• See voucher (coupon codes) that apply to different stores.
• See historical lows.

However, there are less obvious features that are most useful when you look at the Collection tab:

• You can view a filtered list of games. For example, you could look at games you haven't played that have positive reviews that have cards. This can help you work through your backlog, and the functionality is similar to the Backlog Assassins site (Group recruiting topic on Steamgifts).
• You can setup arbitrary tags and groups, letting you filter games by properties you associate with a given game, such as "horror" or "multiplayer." You can add notes, such as whether you won the game on SteamGifts, accessing it through Steam Family Sharing, or have a non-Steam copy of the game (such as one from Origin, uPlay, GOG, or Amazon Twitch Prime).
