To be honest there isn't a safe way. No matter what option they choose to send it as for example 'Gift' 'Service' they can still use a VPN and charge back.
I would recommend using something like Alertpay where the risk's are less, or WU which cut's out all the risk's.
Sypherz is right. On the other hand, if either party scams, you can just charge back/recover. However, I would generally avoid putting alot of wealth on the account, since you never know when it will be recovered.
the only payment method i have is paypal. i refuse to use it on any one except a mod. any amount of gold im selling i sell to nick because i know its the safest way.
