Please tell how we can map following scenario.
When a Customer buys 50 quantities of a certain product, he can buy additional 2 quantity @ 50%.
Depending upon customer choice, he can either accept or reject the offer.
If he rejects, he pays for entire 50 qty without any discounts & if he opts for the offer, he pays full amt for 50 qty & only 50% for additional 2 qty.
This holds good for every additional 50 qty.
Thanks & Regards,
