I've searched the forums on this one hard!

I can't imagine that I'm the only one who's ever had this problem; maybe I'm just not searching the right terms...

I've got a product that has multiple attributes. Each attribute is equally priced at $45. If the customer chooses 4 of them I want to offer them at $35 each; 7 of them, at $25 each, etc.

This isn't multiple units of the same item, which would be Quantity Discounts in the Price Manager.

It also isn't multiple quantities of the same attribute which would be Attribute Qty Price Discount.

It's multiple attributes on one product, where the more attributes are chosen, the less each one costs individually:

1-3 Attribute = $45 each
4-6 Attributes = $35 each, for ex. $140 for 4
7+ Attributes = $25 each, for ex. $175 for 7

I hope this makes sense. I have the product online here:

Can anyone help?
