Its difficult to completely automate the supply chain as incoming FBA shipments expire 30 days after they are created. If you're shipping heavy freight from China this is cost prohibitive. I currently "touch" my inventory one time in-between the source and FBA. I'm working on streamlining that part though.
Be sure that your mfgr isn't running off extra for AliBaba, free markets or other channels. Contract mfgrs are notorious about ripping off IP and product.

Well, what kind of companies do you work with—a printer, and a distributor? Any others? How did you find the ones you work with—and how did you know that they were the right ones? What have you done for marketing—gone to trade shows, paid for advertising, giving samples to the right people, or what? How well is it doing?
