Just my luck

I bought some CDs ths past weekend at Birch Run. They were Trio disc sets, with three CDs each of Mendelssohn and Mozart. Unfortunately I wasn't as sharp as I should have been, because the mendelssohn package contains two of the second disc! ARGH! This isn't the first time this has happened to me. When I bought the "Lord of the Rings" audio book(s), it had two copies of disc 7. I wish bad CD karma would stop hitting me! (Like when I opened up a copy of the Smojphace EP only to find the disc was cracked at the hub. Joy!)
