I USE THE SITE TO CHECK WHO HAS WHAT TO TRADE AND DO I HAVE ANY THING THAT THEY NEED THAT I HAVE TO TRADE. IT MAKES IT EASYER THAN GOING BACK AND FORTH TO SEE WHAT WE CAN TRADE. MANY SITES ARE NOT UP TO DATE AND WHAT APPEARS TO BE GOOD TRADE TURNS OUT TO ALREADY BE IN THEIR COLLECTION BUT NOT POSTED.
