Hardware purchases

Not sure if I am the only guy with two heads, but this is the question. Or, rather a discussion if there is such section.
Might be strange to some, but it might be not to others.

Do you order, do you have a possibility of ordering disks with drivers and OS for your workstations or laptops you purchase for work, and do you get them?
Whether it is IBM, HP, DELL or any other brand.

For years I ordered systems from Dell and asked for disks with drivers and OS.
When the systems are moved to the floor after about 2 - 3 years of office use I quickly reformat the drive with the OS, install drivers from disks and apps from the network and they're 'brand new' and clean.
To me, one guy with over 100 users and 6 servers in two locations to support, burning backup disks for every system is a waste of time.
My Dell sales rep doesn't seem to understand that.
The worst part is that there was an option for purchasing those disks for $20.00, which I chose and spoke to her about and I still didn't get the disks.

Before I contact higher ups at Dell I would like to know what is the general view on this issue.

Thank you.
