I have a lot of textbooks for 2nd and 3rd year INF and COS modules that I no longer need. I'm hoping to get rid of all of them, so I'm willing to sell at 50% of whatever the current shop price is. (They're all in good condition too)
I believe I have books for INF120, INF206, INF320, INF307,INF303, COS101, COS161, COS221, COS261.
If you're interested, and live in Cape Town, email me which books you need so I can confirm that I have the right edition, since obviously the books do occasionally change.
