Good to know that information, I live up in Northern Canada Alberta and I do not think there is UPS center in our town and so I have been using Canada post that have different rules.For USPS first class international to Canada it is about $10 for up to 8 oz which 3 razors without cases won't exceed and between 8 oz and 16 oz the rate the rate goes up to about $18.
The best way to do a pass around I think for international to mitigate shipping costs is you have separate sign up lists. US, Canada, EU/UK, Australia, etc. Once the minimum participants for each list is met then you send it out to the first person on the list. The only 2 shipping costs to figure out to even things out is the first person from the US to whichever international and last person on the list back.
Have some great shaves!
