Frederick888 / PlayStation Store - I'm hella cheap

I get the following error when I run this script and then click on the button that appears:

Uncaught TypeError: Cannot read property 'click' of undefined
    at setInterval (<anonymous>:52:50)

Re: @intrepidOlivia:
If the issue you mentioned happens only when there're no free items available in the current page, it should've been fixed in 0.22.

Otherwise please elaborate the issue.
