Adding a deposit to pre-order
I ordered this plugin so I could take pre-orders. However we are a small store and we do quite expensive items on pre-order only. I would like to take deposits rather than a fee for pre-ordered items. It does seem weird that a pre-order plugin doesn't offer a deposit feature. When using the fee section it adds onto the total rather than subtract it from the total like a deposit would. I am sure most people would want this feature as well.
