I'm trying to figure out how to add a setup fee to some of the items on my page like while configuring a dedicated server how do i add a setup fee for secondary hard drives

I would think the easiest way would be to set this up as a product add-on and attach it to your dedicated server offerings.

now what should i set my billing process to forit to only charge once for setup

well i don't really like how that looks doesn't really look professional
