<< Johhine, take it from me: AVOID COD AT ALL COSTS
UPS, USPS, FedEx, WHATEVER. dont do it.
A: it costs more
B: if the customer is not in or they refuse the delivery you get stuck with the shipping charges
<---got nailed on $200 in overnight freight on bad COD's
if you have to, get a deposit up front. Also, it usually takes 3-4 weeks to get paid. >>
As seller, I always asked the buyer to send a fraction of the payment first as an indication of good faith.
