How does this page work? No matter what I search for I don't seem to get any results.

You have to search the exact name of an item to get it to work.

I did that, but it still does not show anything :( I searched for really common items, like 100 Point Wizard Token and 1 Month Gold Account Medal...

I got results for both and Before I posted the first time I tried and also got results. The CSC/token took awhile to load though, and the page lags a lot because the list is so long

Huh. Odd. I'll try again, thank for your help :)

EDIT: It loads very quickly to an empty page :/

It works for me. Sometimes searches fail on Subeta because you've got a space at the beginning or at the end. If that's not it then you need to see if NoScript or one of your browser's other extensions or add-ons are interfering. Disable them one at a time and try after each.
