It doesn’t seem doable in CS-Cart, can someone tell me if i’m wrong? I really need to get this feature to work.
I want this for all product on my site… when quantity is more than one the price on the additional quantity to be 25% off.
I guess you can think of it as:
Buy one get one 25%off ( and any additional thereafter at the same 25% off price)
Clients must get 2 or more of the same item in order to get a discount.
Any advice? I have been trying to figure this out for days! 
Did you try the Qty Discounts tab? (I think this is what you are trying to do?)
I did look into that, but there are a couple of limitations by using the quantity discount:
a) I can’t use a % discount, so every time the price changes i’ll have to go in and edit the quantity price as well.
b) Quantity discount applies to the first product as well… I want my clients to pay full price for the first item, and 25% off any additional.
Any advice would be great!!
Thanks again.
