Throwing the baby out with the bathwater

Sooooooooo The Rogue and One Night of Sin are both available at BAMM. Waldenbooks said they will put out One Night of Sin when they get it in. They just put out Jamie. So if I go into Waldenbook I will have no choice but to buy four books. What? How can I have the will power to walk in there buy ONE book while they have a buy 4 get one free. And this does mean they will have Master of Pleasure, since I just bought it and it could have been one of my 4. I haven't done the math, is it cheaper to buy 4 and get one free at walden's or cheaper to pay for all five at Wal-Mart prices. Do I chance ordering them, The Rogue, Jamie ONoS from BAMM, then knowing I could get my hot lil hands on them sooner? Cuz if it works like it should, I would think I would have The Rogue and ONoS faster by ordering them and Jamie can wait and would save me from myself and a walden's trip. I guess worse case, I end up with two copies and I am sure I could find a good home for the other. oh you know I still have a 10 cert to use at amazon as well... Good thing I got paid yesterday. Or I could be good and just go home and read the books I have.
