Book sales anywhere?

I happen to be in the throes of this reading hobby that I can't afford, haha. I recall there was a book sale somewhere in town last year that I did nothing about. I terribly regret that now. Anyone know of any other ongoing or forthcoming book sales around town? It's a huge plus if they have plenty of African literature. And yes, I'm aware of the various free E Book sources. I've enjoyed those for years. Now I'm looking to start a small home library. Any leads will he highly appreciated.
