MadisonCali's method is the one I am familiar with, but I do not think it makes a difference whether the item is deposited or cashed by the purchaser. This procedure is more a matter of banking custom than an attempt to adhere to the dictates of law or regulation. The fact that there is relative uniformity in the processes used by many banks is somewhat amazing.
