Mile High will not hold comics, so what was in stock at the time of your order will not necessarily be in stock when they
fill the order. This would not usually be a problem, when
you pay for your order by credit card, because it nearly
always gets filled the next day. However, it can be a big
problem if you are paying by money order or cheque
because the order will not be filled until the money order
has been received or the cheque cleared and by that time
stock of a particular item can be exhausted. This has happened to me before.
