Hi,
I'm having trouble setting up a shipping rule I require.

I have 1 category (Seed) which will always have a flat rate of $1.50 shipping regardless of quantity ordered and other categories that I want to use per item shipping.

Is it possible to set up ZenCart to use the flat rate for all category 1 purchases as well as the shipping per item for anything purchased from another category?

An example could be:
A customer purchases 6 packets of seed and, let's say a dehydrator and some clips which have different shipping costs ($10 and $2) and come from category 2.

Total shipping should be $13.50. Can this be done?

Also, can the shipping be left blank awaiting a total shipping quote as many of the items I sell require individual shipping quotations.
