Friends,
I do buy mine in Silverbird Galleria. It is on Ahmadu Bello Way, Victoria Island, Lagos. The bookshop is on the first floor, don't worry cuz you won't miss it. Contrary to what you may have heard, their books are pretty cheap compared to some other bookshops including those on the mainland. I buy most of my books from there.
Also check out Bookworm @ Sweet Sensation Building on Adeola Odeku Str, VI. Their books are more expensive than those at Silverbird though.
Check out CMS Bookshop at CMS and This Day Media Center @ The Palms Shopping Mall in Lekki. You can't miss these shops as well, they're easy to locate.
You'll definitely find the kind of books you're looking for there.
