I just recently started wish listing games and I am on 179, my question is, am I missing or can I not sort my list by price, Lowest to highest or to set the range of the games I want that are free to like 3 dollars?

Thank You :),

God Bless You and Stay Safe :)

Yes, you can't either sort the wishlist by price or filter by custom price range. Feel free to vote for the relevant community wishlist entries:
