Tools are something people add to their toolbox as they go through life. You never know when you may need them again, even if you get rid of the device in question, a friend may ask you to repair something.
People into repairing things would likely get a full kit of sizes (iFixit for example) and not wish to part with one or two.

Even if someone was willing to sell an individual driver by the time you have arranged for postage or fuel, you may as well order online or visit a localish toolshop.

Maybe someone will prove me wrong but just in case your left hanging and no one replies to your post.
