Anyone Remember?

So my near and dear friend Piper brought up an interesting point. CD clubs. Anyone remember them? You know - those places where you could buy 13 CDs for one penny, then each subsequent CD was $18 (whereas at the time on could easily get a CD for $12 at Best Buy). However, a lot of people had timed it where they'd buy one CD then quit. I think some people found some way to scam the system. Although I assume there was something in the fine print that didn't allow for this. I'm not sure. I do believe some of my friends were in CD clubs, but I'm not sure how they made things work.

Anyhow. Do CD clubs still exist? I imagine i-tunes and the downloading of music drove them out of business. Was anyone here in a CD club? Was it worthwhile, financially speaking? Was it a good deal? Was there a good way to scam the system? Please, do share.
