Thanks for the info.
I think you'd find it would be a lot more to get them out of the country.
I was talking to a supplier about this yesterday. There's a reason that almost no one in Canada offers free shipping. As soon as Canada Post is involved, it's really bad, and you have to always talk with suppliers and tell them don't ship across the border with a courier, or the brokerage fees are high enough that you feel like you need a second job. To ship a package that's about 15 pounds, and the size of a rolling tote across the country, costs me almost $40. An "envelope" similar to what I've had shipped from Sew-Classic will typically run $15 - 20. Hers are usually marked at under $5.
