Add a payment gateway surcharge to checkout
Payment gateways such as PayPal and Stripe charge a small amount for processing a transaction. This code adds a credit card surcharge as a percentage of the cart total to cover that amount. Examples are shown for PayPal and Stripe, adding 3% for each.
Add custom message at payment button
This code lets you add a custom message at the final payment button. This could be a privacy statement, or some instructions about the sale process. You may need to add some css to style this message to suit your site.
