Discounts

I need to apply a discount band to a particular type of customer. For example, we might allocate a 'band A' discount to a customer who was a distributor. This actual discount % in band A would vary according to the category of product. So 'coffee cups' for example, might carry a 10% discount in band A, whereas 'coffee beans' might have a discount of 5% in band A.

This might change to, for example, 15% and 8% respectively in 'band B'.

When an order is placed by a distributor with a band A or B discount allocation, all of the discount percentages would be automatically incorporated into the invoice. Can this be done in HikaShop?

If so, is it also possible to incorporate a quantity discount into the same transaction? So that if a 'band A' customer bought more than, say, 50 coffee cups, an additional discount of, say, 10% might apply. (I guess the quantity discount would be calculated before the band discount was applied).

I hope I've explained that clearly enough, so sorry if it's a bit muddy.
