On one product (category CCDCM), the category discount type is "discount by an amount based on qty," then below, "1-0|11-1|51-2|101-3". Shipped using live weights; the weight is .750 lbs.
On the second product (category PCDCM), the category discount type is "discount by an amount based on qty," then below, "1-0|6-1|21-2|51-3". Shipped using live weights; the weight is 1.000 lbs.
In default category: if I leave the above fields blank, then the discounts based on qty do not work. If I leave the weight blank, I get no shipping costs. If I put a weight in, it chooses the default rate over the category weights. If I put a discount based on qty, it chooses that discount over the category discounts.
Any suggestions? (Thanks---it's theoretically the last thing holding us up from going live right now).
