What?? Really? I have had Nexus for 4 years, was never told that, never done it. I usually travel with 3 friends who also have Nexus. I made them get it or they weren't coming shopping in my car lol, anyways, they have never filled that out either. The past few weeks I have been over almost weekly ..having items shipped Stateside and not once been asked or even noticed the deposit box. I always declare, and more often than not, don't pay a cent which is a bonus!
