accomplished amount apply automatically cart-discounts drop item order price product selling unit widget

First of all, i love e-junkie. I am selling a widget for $10. If they order 20 or more, I would like the unit price to drop automatically to $8 each. How is this best accomplished? I only want this to apply to one item I am selling, not everything.

Thanks :)

Unfortunately, amount based cart discounts apply on the complete order, not just one product .. so what you want can't be done.
