International express shipping

Hello everyone,

I live in Canada and a lot of moth species here have fast hatch times of only 1 week or so. However I know some people from Europe or the United states who would like some species available here and it would be far more reliable to send them as eggs than to raise them here and send pupae. I've been looking at express international shipping yet they all seem to cost about $100 for the envelopes. Does anybody who has experience shipping these species have any tips on which companies or options to go with?

Regards,

Alessio
