It would be handy to be able to order a DVD that has all of the driver software for all of the products that you sell. Maybe even make a downloadable ISO file. Then update it each year. The biggest hassle is finding the right drivers, especially for older products that are no longer available. You might even have a subscription available where each year the updated drivers arrive for Christmas each year. The downloadable ISO file could be updated monthly, or whenever new drivers are added or updated.
