I currently run a website that sells site currency users can purchase with PayPal. The currency they purchase is for on-site items and not physical goods. However, I've had some users request a way to obtain this currency using non-PayPal, non-bank account methods. One thing users have requested is the ability to mail-in money as a substitute for PayPal.
Many of the users on the website are younger and may not have a bank account, so I am not sure what to do. Is it safe to take just cash in the mail? Should I force the users to at least send me a money order or check? I doubt any user will mail more than $20 USD at a time, but mailing money is a bad idea.
So, my question is, is it safe to accept money in the mail?
