Here, we have Half Price Books, which can be fun, but the store is also noisy and crowded and I'm a cranky old asshole and I don't like that. I do go there, but rarely.
My favorite is Movie Trading Company. It's the size of a big Autozone. Most of its floor is DVDs, but they also have Blu-rays and CDs and posters and Funko Pop bullshit. I've bought cool stuff there (the Roy Orbison box set, most of the old deluxe Byrds CD reissues), but I mostly like it because it's quiet.
As for 90s digipaks, I hate most of those, too.
The worst one for me was Yo La Tengo's "I Can Hear the Heart Beating as One". Really nice fancy digipak with an awful CD spindle that broke if you wanted to hear "Deeper Into Movies" more than twice.
These days, the best CD packaging involves no plastic at all (other than the disc itself, natch). It's all paper and cardboard. IT RULES.
