Looks like Music Trader got bought out by Into the Music.
When did this happen?
Into the Music website notes a 2nd location, if you scroll down a bit, same address as Music Trader...
That's really sad, because, while Into the Music is "best of breed" due to not just being a place to purchase optical media (CD, DVD, BluRay), but also is a great place to purchase LPs, 45s, cassettes, videotapes, and listening supplies (sleeves, cleaner)... it would have been best to have still at least another competitor to keep ItM "on their competitve toes".
Music Trader specialized in CD, DVD, "new" vinyl.
