Where in Colombo or on online in Sri Lanka can I buy used or new school textbooks or CD ROMs written by western authors? I am particularly interested in IGCSE Physics & Maths and ESL intermediate student books.
I don't know if you may already have checked with them if not try British council in SL. If they don't have the books you are looking for at least a visit to the place will help you to make contacts whom may can give you further tips. Cheers!
