Hello!

I have an issue with discounts which is a little strange. It's probably best to explain it with some examples.

Item X is a product that has a discount applied by line item quantity (minimum 1, no maximum) such that a customer always get's a discount on each instance of item X they buy.
Item X costs 3$

Item Y has no such special discount
Item Y costs 25$

There is a global, group calculated Volume Discount set up such that if a customer spends over a certain amount on a transaction, they will get a % discount.

Case - user buys 2 item X's and 1 Item Y. We would expect that both item X's would have the discount applied, and item Y would have none. And that's what happens.

Case - user buys 2 item X's and 100 Item Y's, We expect that all items would have a volume discount, because the criteria is met and because the volume discount saves the customer more money than the individual X discount and thus overrides it. And that's what happens, all good.

Case - user buys 300 item X's and 1 item Y, we would expect that the volume discount is again applied to all items, BUT we are getting only volume discount on our item X's, and no discount on item Y. This is the problem.

I'm wondering if this is fixable via the administration of discounts, or if it is an issue in the Commercebuilder's Calculate_GroupingMode method.

Thanks for any help !

How exactly is the global volume discount defined? What is the minimum amount required for this discount to be applicable?
Are product X and Y in the same category?
What is the discount calculation mode set in store settings?

thank you for your reply! here is our setup for volume discount



The discount for item X is scoped as 0 categories 2 Products, the volume discount is global.

the products X and Y would belong to different catalog categories

Thanks for any help

*Edit discount mode in store settings is 'Group by Category'

I understand that the volume discount above is what you are expecting to apply on all products when you buy 300 items of X and 1 Y.
Y is priced $25. In the discount defined above, it says that if line item price is less than 300 the discount percentage is 0%. That is what I see happening.
