To our friends in the USA:
Canadian companies are now required to pre-pay tariffs and then pass the costs on to our US customers,
making it impossible for us to provide our kits at a reasonable cost.
We encourage our American customers to shop locally, and to support the fine folks at Clean Air Kits;
They have graciously offered to redirect inquires from their Canadian customers our way,
and we are following suit to help lessen the impact of this trade war until things get back to normal.
