Concordia Publishing House is one of the few publishers that I routinely use that has substantial sales on some of their music products. Vendors like SheetMusicPlus will often have rotating 20% sales on different publishers or types of music (e.g., choral), but CPH usually has a limited selection of choral, handbell, organ, and piano music at significant savings (50% – 75% off). If your congregation subscribes to Creative Worship from CPH, you can also work directly with their Music Department to order "suggested" products at 20% off. I know this sounds like an advertisement for CPH, but it's more of an FYI of how to make a music budget stretch further (assuming you have a need for their products).
One word of caution: just because something is on sale does not mean you need it!
As I scanned through the latest CPH Music Warehouse Sale, I've listed a handful of organ music items that are frequently on my music rack (and a book about handbells) with the thought that someone might also find them useful. If you're looking for other recommendations, Kevin Hildebrand normally has organ and choral music reviews in each edition of His Voice from the Good Shepherd Institute.
