Thanks for the reply.
Actually just heard back from them today, and got my USPS quote, so will place an order shortly. They were very apologetic about being late getting back to me. Hoping it's just indicative of a small company getting bigger and busier faster than planned, rather than apathy kicking in. I'll report back later on how it goes.
Sorry for the delay, you probably don't need the info now but yes I did go USPS and got a 2 keg premium kit minus the co2 tank. Shipping was $60 and duty was $14 when canada post dropped it off. Very good deal I thought.
