The World Computer Exchange
The World Computer Exchange is an incredible organization that has chapters all over the world.
Their mission is to provide computers to those in need.
However, they do have some stipulations for how the computers should be utilized.
Be sure to check out their website for all the details.
Craigslist may not seem like an obvious choice, but most people don’t realize that it has a free section for each city it serves.
It’s worth it to check to see if you can find a free laptop or computer.
I’ve seen one here or there that someone just wants to get rid of because they upgraded or are moving.
Even if it has something wrong with it, you may be able to find a tech-savvy friend to help you out and fix it.
There are more results I can find from google. Please also check with local organizations/companies/churches for used computers.
God Bless you and your family!!
