…n stuff instead.

How to use:

• Find a local enrollment code SKU in your ecommerce service (or create one if none exist).
• Modify the hard-coded enterprise catalog UUIDs to match your local test data.
• Go to http://localhost:18130/basket/add/?sku=YOUR-SKU
• Fill out the form and submit.
• A new Enterprise Customer is created (or existing one, based on the org name provided in the form) automagically.
• A new enterprise coupon for the course and your enterprise will be created, payment/fulfillment should succeed.
• Go visit the enterprise admin portal at http://localhost:1991 and go to the Code Management screen.
• You should now be able to manage vouchers/codes for the coupon that was just created when you checked-out.
