After some playing around the 1.5 beta 1 release, it generally looks fine. Just want to ask if you can do a minor improvement to 'shipping'. I think there are many companies charge customer shipping rate based on 'quantity' or simply weight of product; for services on the other hand, urgency for delivery is usually considered as important.
Therefore, if you could enable a dynamic price for shipping, it would be a lot better - for example, if quantity is 1, shipping is £1 for 2 days delivery (the 2 days delivery is 'drop down' choice from shipping). However, if quantity is 5, shipping should be, say £5 for 2 days delivery.
In summary, As the quantity changes, the shipping/delivery should also reflect a change to the total price.
Gravity Forms customer.
