Second hand books for Brass Treble Clef

[Okki]

Hi. My DC's play a Sop and Eb Bass. I'm looking for books but don't really want to pay £10 + for new ones. Is there anywhere I can get second hand ones? We quite like the Brasswind publications. I especially want to get a selection for the bass as DD has taken to it like duck to water. She got a distinction on her grade one after playing it for a month and is now working towards grade 3.

Thanks.

I usually just go to Abebooks for music books and there's a fair amount on there. Also charity shops - obviously that's a game of chance but I've got some useful things, especially beginner stuff / tutorial books. I don't know of any music-specific secondhand booksellers I'm afraid!

Thanks. I looked on Abebooks but couldn't find any. Must have been too specific - I shall look again. Thanks.
