Hello,
I have removed the delivery infomation step in my store as I am running a delivery service and need the shipping addy and the billing addy to be the same(mainly for security reasons). I would like to figure out a way of adding a handling fee based on the percentage of total cost of products selected for delivery.
Can anyone make a suggestion about adding a percentage based handling fee in a seperate line to the checkout confirmation page before it is processed via paypal(the only method of payment I will be using)?
Thanks in advance!

It would be a huge help.
