you should NEVER go ahead and send out something you are selling until you have cash in hand...when you go to walmart they do not let you just have it, and send in your payment...no matter who it is or what it is...you are responsible for protecting your interests and if you just go ahead and send away and wait...well, the wait can easily become forever. and possession is 9/10 of the law...once you turn over your item it is no longer yours...so don't give it up until you are paid. there is no reason to be waiting for the 'check in the mail' or broken promises.
