Shopify calculates Canada Post shipping estimates at check out.
Please note that at this time, Shopify does not recognize envelopes as a shipping option.
Some of our products with a slim profile (ie the 30 & 60 gram packets) meet Canada Post's requirements for $3 envelope shipping, as they are less than 1" thick.
Please note that the 100 gram pouches are more than 1" thick, so cannot be shipped by envelope at the $3 rate.
If you would like to purchase a small volume (1-4 units) of our products with a slim profile, please contact us via email to set it up directly, rather than through Shopify.
Thanks for your patience.
