it's natural for some people to get interested on that particular item and make reservations on it no matter what... and in the end if they still can't acquire the required money then they tend to back-out...
it can't be evaded that some people like to mess-up with somebody because they see entertainment in it...
in this small world there are also some people who don't take reservations seriously...
since these factors are reality and they can't be denied, so the best thing to compensate
with all of these depends to the seller...
anyways... tnx for the heads up.. it's very useful for first time sellers..
