Just a note that I've updated the script. The instructions for downloading and running it are still the same as above. Mostly bug fixes, but also some small new features. You can now specify the timeout between updates, and manually update, if you want. These options are all in the menu. Updates also now happen asynchronously. So, the GUI will show up right away, and updates shouldn't affect the application in any way. I've also added a bunch of comments for anyone looking at the code. Finally, you can now put the application in full screen mode.

There's a small bug where the text of the item name won't wrap if it doesn't fit on the window correctly. I tried fixing this, but my fix didn't work. I'll have to try again sometime.

I plan to implement a "Buy" link, that will open the browser so you can make your purchase. I'll see what I can do about adding "shirt", "wine", and "sellout" tabs.
