Always stay safe! It is safer when you trade locally, you see the goods before paying. Avoid using payment / transfer methods such as Western Union, this is the same as sending cash to someone. If you do not trade locally use a service such as PayPal, this can offer you some protection, see for terms. If it is a business that you are purchasing from, paying with a credit card can offer you some protection too.
