I am surprised they aren't Brazillian. Some Brazillian friends from school did that, they would fly to Miami to go shopping, buy game consoles, etc.

Brazilian customs figured this out awhile ago, be too obvious and you’ll get one hell of a fine.

If shipping then yes, customs got stricter thanks to Shein.

If flying then you can bring up to 1000 USD of stuff tax-free every 30 days. On top of a personal phone and watch. Plus 1000 USD of stuff you can purchase at the duty-free shop once you land.

A brazilian coworker bought a suitcase on his trip here (circa 15 years ago) and then bought a playstation and an xbox to bring back.
