This was covered in at least two previous threads...which I think were both yours, Rick!
I think the whole deluxe thing started around the beginning of the decade. Universal began unleashing a slew of them and Rhino and other labels eventually followed suit.
It's another cash cow and way to rope more money out of people...like Jimbo, you. a few others here and probably me.
However, I've waited on many of them to become available via BMG music service, waited for a big sale and gotten many of them for around $12 to $15 each max.
