Is there an original of Ibert's Flute Concerto for LESS than $50?

This work, which is under copyright, is published by the French music publishing firm of Alponse Leduc. No mater what the composition, all of Leduc's music is expensive. A European site as it selling for $78. There is no way around this one since they are the only publishers. You don't state where you live, but should you live in a location where there is a music school or a college or university with a music department, I would definitely check their music library for the music rather than pay $55 for it. Sorry.
