How It Works

1. Checkout Validation: The plugin checks the customer’s billing email during checkout (both classic and block checkout)
2. Restriction Check: It compares the email against the authorized list
3. Product Verification: It checks if any cart items are restricted products, categories, or tags
4. Error Display: If restrictions apply, an error message is shown and checkout is prevented
