[ic] Combining Product with Discount

[Henry Ho]

Hello,

This is the scenario, I hope this feature can be
implemented on Interchange.

Product A: $9.99
Product B (Add-on to Product A): 
Pricing: $4.99 purchased alone.
         $2.99 purchase with Product A.

If a buyer purchase product A and also include product B,
how do I set a the special pricing for Product B of $2.99.

Thanks,
Henry
