Discount priority

[chipset]

Hello,

I have PS 1.6 and I use quantity discount. If You buy 1pc of product - no discount, if You buy 2pcs of the same product You have 2% discount.

It working, but if I have discounted product, I have a problem:

1pc Product is $100 - discount 50% = end price is $50/pc - it is OK.

2pcs Product is $100, NO other discount! - quantity discount 2% = end price is $98 - it is NOT OK for me.

 

How I can use quantity discound AFTER other discount like this:

2pcs Product $100/pc - discount 50% = $50/pc - quantity discount 2% = $49/pc

 

Thanks
