While the "CFLC" approval process takes only a couple of minutes to do online, the first time an out of state dealer tries it there is a sign in process. However, the whole thing is fairly easy.
The USPS has tracking available through the registered, confirmed, etc. services. Not as precise as UPS, but you can track.
Just call him on Monday and ask if he has shipped, ask for the CFLC approval #, and/or the USPS #. Since you used a credit card your funds should be pretty safe as there are safeguards.
