Hi Grant,
I did manage to do a few bulk uploads but have not really had time to continue working with/testing the ecommerce module recently. Unfortunately I don't have access to my test system just now, but it looks like the product_id needs to be an integer (check out the table definition in www/doc/sql/ecommerce.sql). Also another problem I had encountered was something to do with the ns_queryget csvfile not working with nsd8x and I had to run the nsd76 aolserver instead. Hope this helps. I'll be able to look at specifics on my own setup tomorrow if you have any other questions. I had also created additional pages to help bulk upload the categories and subcategories that I can send you if you like.
