Concealed cash or "cc" as some people say is when a person sends you cash money in an envelope, say wrapped in a piece of paperl or a card. It is okay and time especially if you have a great listian with a good record or statistics you can trust them mostly, but there is no way either of you know if it gets lost in the mail. Though a few accept it as the shipping payment, and I have many times before, I like paypal or a money orders. PayPal is quickest, and then you have records: tracking numbers are free and postage labels are super inexpensive compared to post office prices...it is very easy to set up a paypal account. But the nice lady above is probably in good standing!!! So sometimes in the next auction you have you can put how you prefer to receive your shipping fee. Thanks!!!
