I need help with http://steam.tools/cards/

Hi Nonobisha, what exactly are you looking for?

I have used the site a couple of time to check out wich badges were cheaper to craft (during events).
Once you log-in through Steam Open Id you will see all your trading card info listed and can apply different filters depending on what are you interested

You unmark left the checkboxes owned cards / owned games and then click on the tab set price to list it from low to high
