how does the escrow work?
The buyer would send the desired amount to a trusted third party. The third party will notify the seller that the money is received. The seller then sends out the product and once the buyer receives it, the third party releases the money to the seller.
OR
buyer gives bitcoins to the escrow
You ship the item to the escrow,
escrow verifies the item
releases the bitcoins to you
escrow ships item to buyer
That could also work. Basically it's a transaction involving involving a third party to protect money for both the seller and buyer.
