I'd be interested in some of those! About how much would shipping run to SK, Canada?
I put in a random postal code for SK, Canada, and here are some general rates the US Postal Service website gave me, for items packed in a regular box:
1 pound in weight: Priority international for $37.50, First Class international for $16.00
2 pounds: Priority $40.55, 1st $16.00
3 pounds: $43.60, $25.25
4 pounds: $46.65, $37.25
For your actual postal code, it might be different, but probably not by much. I know international shipping has gotten insane in the past few years. I would not charge any extra for handling or materials or anything, just actual shipping for the service you prefer.
