I've purchased Dhamma books before from...Buddhist Publication Societyhttp://www.bps.lk/
... before and found them to be very good... seemingly only charging "cost price" or thereabouts for texts and postage.
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.
