Is it safe to accept money in the mail?
On your end of the deal, the biggest risk is probably counterfeiting. That said, I'd think that most of the downside would be for the buyer since they would have no way to prove that they paid you.  Perhaps a better alternative is to send the items COD (Collect On Delivery aka Cash on Delivery). The USPS and some other carriers offer this service, which can be an effective way to remotely negotiate a cash sale. I double checked the USPS site and they do accept cash for COD deliveries: Recipient may pay by cash or check (or money order) made out to   sender. (Sender may not specify payment method.) You might want to double check this if you go with USPS or FedX.
