Ethical buying is a veritable hornets nest. In this case I refuse point blank to deal directly with Amazon (as distinct from Amazon Marketplace, where a lot of small traders ply their wares), because of the lousy way they treat their workers, and because they won't pay their taxes.

The Book Depository I'm not sure about. Yes, it was taken over by Amazon several years ago, but I've seen nothing to indicate TBD workers are treated in quite the same barbaric fashion as Amazon workers. Does anybody know whether TBD workers managed to retain their trade union rights and working conditions, or whether they went by the board when Amazon took over?

I should add that I haven't bought anything from TBD in God knows how long, so from my point of view, the question is somewhat academic. However, it would be handy to know in case a raving bargain ever crops up.
