Shipping & Delivery

We use a form to obtain sender/recipient information for floral arrangements.  The form has an option for pickup or delivery.  When someone selects a delivery, the site does not automatically add the delivery charge during checkout.  During checkout the customer is required to again select pick or delivery.  Many times they either do not select delivery or overlook it and the delivery fee is not added to their completed order.  We have to spend time following up with the customer to accept payment for the additional fee.  It would be convenient and more efficient if the site would auto generate the delivery fee once it's selected on the form and the only shipping option during checkout is delivery if selected as such on the form.  Not sure if that's possible?

It would be better to ask the customer about pickup or delivery on the checkout page, rather than a product form. This will ensure that the correct charges are applied depending on delivery or pickup. It's difficult to be more specific as you haven't provided a link to the site.
