15% off TOTAL order?

**Paulad** · 21 Jul 2008, 12:56 AM

I need to know how to do this by weight. In other words if someone buys one lb of any product in the abc category they get an extra 10% off.
I also need to do it by weight across categories. I am stumped. Thanks for any help. Paula

Regarding the bug in the add-on... I'm not sure that's really a bug. I think the standard protocol is to add tax before the discount.

It may vary from state to state, but I think the law is to apply sales tax to the original price. I've always noticed this in all the stores that I purchase discounted items at.

I see the Price Sensitive Discount add-on is written in 2006 for Zencart v1.3.5 - has anyone installed it on v1.3.8a and can confirm it's compatibility. I would think there would be no problems, but if anyone can share experience... Thanks in advance

I don't know if the Price Sensitive Discount is compatible with 1.3.8a, as I didn't end up installing it.

But I did install this Quantity Discount module that worked quite well, and had easy setup:
