A wire transfer is the process of transferring money from one bank account to another. Wire transfers can be made through banks, cash offices, or independent companies like Western Union. Because wire transfer payments cannot be reversed, it is not advisable to use them as a payment method unless you already have an existing relationship with the individual or company.
Instead, you should use safe payment options such as PayPal which offer a level of protection if something goes wrong with your shipment or wholesale order.
