Is buying a "pre-filled" water cooled CPU system online crazy in the winter time?

There was an awesome deal online but I'm worried about the package freezing during shipping. I live in Canada and tonight it is supposed to be an ungodly and unforgiving minus 40 Celsius. Instead of receiving an expensive block of ice, is this a "buy local only" item? Anybody know if it's just pure water in these systems?
