Hi.
Ubuntu linux will send you a free CD.
https://shipit.ubuntu.com/ This is a good distro for people who are new to Linux - although I do not prefer it myself.
I don't know whether there are newsagents in Lokoja who stock Linux magazines. A Linux CD with a magazine is how I got started.
There are also online shops which sell Linux for a fairly low price (compared to Microsoft ...) You can search yourself or try looking at the ones advertised at

Good luck.
