Other suggestion
I suggest one might look into World's Greatest Magic's DVD/VHS on money magic.
Certain effects discussed by Jay have another take or are done differently. The 2$ window effect is performed inversely by Michael Ammar. You start with a 2$ and you split it in two and you join them back together. The handling is quite different also. I simply love Jeff McBride's story about the bills coming from trees in his T&R effect.
