I've surfed the threads pretty thoroughly and can't find this particular solution.
There are a few similar, but not quite what I need.
I offer a tangible widget for $20.
I have three other widgets, A, B, and C. Also for $20.
I would like to offer the buyer a half-off discount on A, B, and/or C, if they add it to the cart.
Or, if they add two in any combo, the get half off each.
So they add main widget to the cart for $20.00. Then they add A & C to the cart, and I want each of these to be $10.00.
I could create new items for A, B and C and price each half-off, right? BUT...they buyer could simply add these to the cart, without buying the main widget.
Is there a way to discount items and require a cart minimum, or can you 'block' items that can only be added to the cart when a certain item is already in there?
