I just tested the fix for the category discounts being applied within the test site http://www9.smith-consulting.com and they are still not working. I also installed the new download 3.07 to my site and they are not working there either??????
the test that i did on your site:
Premium Channel (category) has discounts that apply to it.
Fitness Channel & Spanish Channel (are products that are under the Premium Channel category)
If someone selects FITNESS CHANNEL and SPANISH CHANNEL there would be a discount for more than one Premium Channel.
It's not working.
