Here a cheap ten-pack DVD-R costs approx $10 (because our government
collects money for the media industry). Anyway I agree, it would be
cheaper than a 32 GB pendrive. So if the pendrive cannot be used for
anything else, DVDs are much cheaper, particularly in your country.

Are you intending to install the system and send the DVDs as backup, or
will the end user install the system from the installation media (DVDs
if you find a method that is fairly easy to use)?
