Samurai will eventually get there at some point. Likely first in Canada in the next month or 2 and then we'll explore Europe. There is SO MUCH DEMAND for international that it's overwhelming. We really wish we could help out... the truth is that each country we enter is really complicated and we have to tread carefully because we need to ensure that our partners are great, that we can provide round the clock support, etc. We just aren't there yet.
Fill this out and we'll let you know when we launch in Canada: https://docs.google.com/a/transfs.com/spreadsheet/embeddedfo...
