WHEN THIS PAGE LOADS, YOU CAN SEE FROM THE CODE THAT "begin_checkout" IS PASSED TO YOUR GA
If this were a real store, you would see your shopping cart details here and the start of this process. In most cases, this process starts automatically. We just had to create a page to begin the process to pass the details to your GA.
* When you click the "Enter Shipping Info" button, there is no actual shipping info being collected. We are faking it. There will be a form for you to enter info but we are not collecting or storing it. We just fake it and enable a button to show that shipping info was passed. In a "real" system, this information is collected.
