Funny, I just came through, having declared purchases on my online form and to the officer doing the passport check, and he said “you’re all set, go through” and reminded me that because I have both MPC and Global Entry I could have gone to the Global Entry kiosk (the process is so opaque IMO). I expected to see officers after picking up my bag but nada. At the exit there were four, standing around. I asked about paying duty, and they asked if I had meat or cash then waived me through. 🤷♀️ No meat, no cash, but a horde of cheese and a few other things
