Sorting System Idea for the Rito Games Store on League of Legends.

While Rito has an Ascending and Descending order in price as a sorting feature already, sometimes i just wanna see what i can afford and nothing i cant, like a checkbox that removes all objects i cannot afford or a page that only shows objects i can afford. if they used the second idea they could easily keep the rest of their sorting system the exact same.

Anyone with me?
