/*
=== INSTRUCTIONS ===

1. Open Amazon wishlist page
    
2. Make sure all items are loaded. You may have to scroll for a long time if your list is long. Scroll until the **END OF LIST** marker is shown. 
    
3. Once all items are loaded, copy and paste the script below into the console, followed by hitting the `enter`/`return` key
 - On Chrome console can be found via: ` Ctrl + Shift + J (Windows / Linux)` or `Cmd + Opt + J (Mac)`
 - On Safari via: `Option + Cmd + C`
 - On Firefox via: `Ctrl + Shift + K` or	`Cmd + Opt + K`
   

4. The page will turn into a formatted table of your items. You now have a few options: 
 - select all the items w/ `ctrl + a` and paste it directly into an Excel sheet. 
 - save the webpage as an HTML document/archive page/PDF (book marking will not work!)
 - other ideas I may not be thinking off
