yeah if you still have a stub off a money order you can have it tracked(has a tracking number on it). and they have to have it cashed at a bank as far as i know.
this is exactly why i'ma keep my commission lists small. i don't want to take to many people on and get over whelmed. and i hope i never end up on the bad side of this list. =\ almost makes me scared to start my store. but it's coming xD
