Product A:
Small, $220.00 (Base price)

Medium size +$45.00 (via modified choice)



Volume discount... buy 2, $200.00 each. ($20.00 discount each unit)



1. Buying one medium results in a cost of $265.00. This is correct. ($220+$45=260.00)



2. Buying two medium results in a cost of $400.00. This in NOT correct. It should be $490.00. ((($220-20.00) x 2)+($45.00x2)) = $490.00



The price modifier costs should be added AFTER the quantity discount is calculated. It seems the price modifier is being ignored altogether if a volume discount is triggered.

No... I'll likely not be using this feature anytime before SP3 or whatever comes out.

It is a bit troubling that modifiers are ignored so completely though.

Also, in most businesses, a volume discount -deducts- from the price. IE: "Buy two get 10% off!!" Couldn't a vol disc be treated as a modifier and subtract from the unit price? Seems an easier way to handle this - short of creating a 'special offer'.

The modifiers aren't ignored completely, in fact, the issue is that the modifiers are actually being factored into the process. You have a line item for 225 and then a modifier adds 45 dollars so you end up with 270 dollars as a base price on the line item. Then when the volume discounts are applied we were looking at the base price on the line item and using the volume discount amount to figure out the discount that we needed to apply. So essentially we ended up getting the difference between the modified value and the volume discounted value. It was done this way so that we wouldn't have to pull the products from the database, but in this instance it is affecting the expected behavior. We are changing this feature to work as you would expect and it will be included in SP3.
