Is there a way to delete registrations for products that we have decided not to re-stock?

To remove a product from the InStockNotify system:

Step 1: Open the app to the Registrations -> By Product Page

Step 2: Search for the product(s)

Step 3: Select the product row(s)

Step 4: Click the delete button

Step 5: Choose to send an email first or just delete the product

Step 6: (optional) Customize an email to send customers that were registered for the product
