Hi. I have a buy-get scenario to implement. Any ideas on this would be appreciated:

- There are three groups of Buy items each containing say 5 items.
Group A: Item1, Item2 ... Item5
Group B: Item6, Item7 ... Item10
Group C: Item11, Item12 ... Item15

- There are three Get items.
Item16, Item17 & Item18

The scenario is: Buy Any one from each of the three groups and get one item free. However, the free item can be chosen by the customer.

- Regards, Raghu
