Apologies if this question has been asked. I saw similar questions, but not this exact one. My wife and I are visiting friends in Montreal from Fri-Sun. Stopping at Alchemist on the way up for at least 2 cases of beer (maybe more). From what I understand, you can take one case per adult duty-free. Most of, if not all, the beer is coming back with us to the US (we may break open a four pack, but that's it). Will I have to pay any tax? Also, will I get taxed coming back to the states even though it was purchased in the states? Cheers!
