We do a lot of sales on account. Often times there are promotions where the item (e.g. Dog Food) is given a quantity discount. Buy 15 bags of dog food, get the 16th free. I know RMS is setup to do this discount if all 15 bags are bought on one trasaction, but who would buy 750 pounds of dog food at one time. Is there a way for the system to take care of this discount using the customers purchase history?
Thanks
