[christopherjohnson1]

User Story

As a user, you should be able to enter your email into a form if a product is unavailable

AC

WHEN you navigate to the merch page AND a merch item is unavailable THEN you should be able to click a button to launch a form AND you should be able to enter your email address to be notified when the merch item is available AND a window alert will confirm your submission

Dev Notes

• the merch cards should display Unavailable for any merch item that is out of stock
• the merch card should display a button that says Notify When Available that has an event listener
• the event listener calls a function called availabilityForm that will add a Bootstrap form to the DOM - https://getbootstrap.com/docs/4.0/components/forms/
• on the form, the user should be able to enter their name and email address and click a button to be notified when the merch item is available.
• the form submit button should have an event listener that window alerts when a successful form submission has been completed
