YMMV because trade value fluctuates even over the course of the day. Monday last week it was $135 in the morning and $125 later that afternoon. You don't have to be a pro member to get it. Not a bad deal if you were going to dump your XBox anyway. I'd call the store before going to make sure though.
Also, that assumes your console works and you have the power brick/cable, A/V cable and wireless controller.
Amazon trade in is $196 right now
Best buy online says $65
