I just noticed in my Edward R. Hamilton books on the cheap catalog that they are selling Mel Bay's Dulcimer book, plus CD, for 5.95.
"Intrduces 25 mountain dulcimer players, and provides sheet music, and an acompanying CD with songs, such as Bobcat Ramble by Janita Baker, and Jerry Rockwell's Whisper from the Hillls. Photos, 95 pages, paperbound, published at $24.95"
Even with the $3.50 shipping (U.S.) this seems like good deal, especially as shipping cost stays the same no matter how much you order (plus the fact that hearing Janita play Bobcat Ramble is worth the price of admission alone). And they have a no questions asked refund guarantee.
