Escrow.com is a safe third party option that holds money in a ?trust? account until the buyer receives the goods. Once goods have been cleared by the buyer the money is released to the seller. Note that you should only use Escrow.com and no other services advertising as 'escrow'.
There seems to be a fee when using this service. Here's the link to their fee calculator:Link hidden: Login to view

Without or without escrow, I would still not recommend that you use wire transfer as a method of payment. Generally, it is still not considered a safe way of paying for your orders.
Hope this helps. Cheers :)
