have the guy mail the cheaper one first. I tried this trade already, ended up not getting my galaxy black grill. Mostly DHL's fault...dont use them! The good ol' postal service got my chrome grill to Oregon in 3 days.
a little advise... take the chrome trim off the grill shell. Its lighter that way you'll save on shipping ($17) and you dont have to drive around without radiator protection waiting for the mail.
Also, shipping insurance is cheap the whole grill assembly from nissan is about $450
