When you delete your products, do NOT delete if there are any products still in them. If you do, you will never be able to delete these products without going through your database and finding all associated records to each product line and removing them manually.
To me, this is a HUGE flaw in the system, and can be very upsetting when they look at your products.rss listing and there's products there that aren't available for real.
I'm thinking this is a huge fix, that ViArt needs to address ASAP.
