I've purchased Dhamma books before from...Buddhist Publication Societyhttp://www.bps.lk/

I've ordered Wisdom Publications translations of certain Nikayas (as translated by Bodhi, Nanamoli, Walshe) from Amazon because for texts like that, the discount offered by Amazon was enough to offset their ridiculous postage rates to Australia.

What is the final conviction that comes when radical attention is razor-edge sharp? That the object of the mind is mind-made (manomaya). (Ven. Ñāṇananda)
"If you have always believed that everyone should play by the same rules and be judged by the same standards, that would have gotten you labeled a radical 50 years ago, a liberal 25 years ago and a racist today." (Thomas Sowell)
