In Topspin, you can bundle multiple items together in Packages. First, just make sure you've created some products in your Products tab. Once your Products are ready, it's time to start bundling them in different combinations! 

1. Click "Add Product" and then "Package"

2. Select the products you'd like to bundle together and click "Add To This Package". Click "Save Package". 

All set! Your Package is now available in the Products section of your account!
