Visiting the site on a desktop works fine, but it's less idea for mobile devices. In particular, the drop down selector for adding items to the "Items You Want" and "Items You Have" lists are awkward to use (tiny touch targets and multiple touches required).
SOLUTION:
The site should be converted to a design more suited to mobile devices and controls re-worked to allow touch interaction as well as mouse interaction. Ideally, this would be done by detecting the device's size/input method and making the appropriate changes to the UI automatically.
