Volume discounts on an order

[shazaam]

Hello,

I am trying to create a series of volume discounts based on an entire order.  Has anyone got a suggestion on how this can be done?  What I am trying to set up is a series of discounts at the order level that says if the total dollar amount of an order is between x1 and y1, they get a z1% discount.  If the total order is larger and between x2 and y2, then the discount is z2%... and so on.

Can anyone help me out? I am using Joomla 2.5.5 and VirtueMart 2.0.6
