I installed the lettermail version of Canada Post and it works well except that it doesnt seem to calculate sizes within the lettermail category. I created a 2cmx2cmx2cm product to test, 1g weight. This was accepted by Canada Post and priced at $.52. However because of the size it is non-standard and should cost $1.15.
I could change the tables to make everything cost the non-standard rate but then valid small packages would cost more also.
Any suggestions?
