Line item (product level) discount

I'm running a sale that is a "5 for $20" offer. Each of the eligible products is set at $5. When the code is applied, I need the eligible products to drop in price to $4. Can AwoCoupon change the price at the product level, or only at the order level? Currently it seems like I can only do $5 off the order. I need the line item discount to be able to process the orders automatically into my ERP.

VirtueMart 2.0.20b

Thanks!

Hello,

AwoCoupon does not change the product price. But here is some code that can assist in altering the product price within the cart:

Thanks for the reply. Unfortunately, my business process requires this to be a system change, not just a client-side "visual" change. Our ERP is ancient. Oh well, I'll have to figure out another solution I suppose. Thanks!
