As in isthereanydeal.com, it would be nice to add a green “Passes” tag for games that meet set requirements (for example, price under set threshold).
I’ve also been wanting this feature, but I just noticed that there’s a filter in the sidebar for “Discount: Meets wishlist price”! I realize that’s not quite what you’re asking for, but it fulfilled what I was looking for and I hope it does for you as well
