I have products that each consist of a number downloads (setup as option name/value attributes.)
Each download is priced separately at $0.79.
However if you buy all of the downloads for a particular product I need to apply a discount.
1 product containts 10 downloads at $0.79/each (total of $7.90)
If you buy all 10 though I want the total price of the product to be $6.99.
How can this be achieved?
I tried to do this with attribute quantity discount, but it seems there's no way to make it take account of the number of selected attributes.
