i have been caught at the border, the seven year flag and huge fine isnt worth the savings
the guys at the border have the right to check you bank account, email, etc etc
been there... done that... now im 100% legit when i cross the border, my fine was 5x what i would have paid if i had simply declared what i had and each time i go through the border im pulled to the side and my vehicle inspected along with good, i have to have complete documentation detailing the transactions for what was purchased
