Buying CD's...where?

To bad this forum isn't called "Media," I didn't see anything to fit the music genre.

But I'm wondering, where is best place for the price to be buying CD's? I used to subscribe to this monthly mail order place where they send you like a dozen initially for a penny, lol. They were good prices but continued to rise over the years making it pointless to order from.

I'm not into new technology for obtaining music, I like the old school CD. :)
