You have to register with them first (which is painless and easy) and then you can send stuff there. They have an address that you can use (either a PO box or street address - I included both on all my packages) to send stuff there. They will notify you when your package gets there by email but sometimes they are back logged, so I just phoned. For all 5 of my packages, I paid around 15.00 dollars. Sure beats crappy Canadian shipping prices
it's right in sweetgrass, which is the little town as soon as you cross the border. if you make a trip of it it is SO worth it as beer is insanely cheap. 24 pack for 20.00 bucks versus 40.00 here. Even if you went over or had to pay duty on it, you still come out on top. It's the hard liquor that you get slammed for. Anyway - thought I'd mention that incase your fiancé is a beer drinker like mine. I'm all for supporting the Canadian economy but hell, we are paying for a wedding - cheaper beer all the way!
