Apparently, this is as low as they're gonna go from now on (don't forget the discount codes--CMG3 and CMG4?--that give you an additional 10% off). I think they learned their lesson after the big '06 Blowout, in which they basically gave away (at 3 bucks a pop) brand-new OOP CDs that were going for ridiculous prices on Amazon Marketplace, etc. This time, they even priced the Limited Edition OJCs a bit higher than regular--albeit some already OOP--OJCs.
Still, with the sale prices, plus the additional 10% off, plus the buy-9-get-1-free, plus the free shipping for orders of $50 or more, it works out to be a decent deal (around $8 give-or-take for regular OJCs), and a chance to pick up some OOP OJCs for reasonable prices.
