FREE GOODS

HI,

My customer would like to award free goods in his orders.

For example, when a customer buys 10 different items of an item group, he will have one free. This free item  must be the cheaper item from the list that the customer bought:

3 items A - unit price = 100

5 items B - unit price = 150

2 items C - unit price = 200

the customer must have 1 item A free

DO someone know if this is possible in standard (JDE V.9)

Thanks for your help
