HiPCTech:
Well, they are not in my admin configurations... In the version that I have, V1.3.7c, these settings are only in the files.
Which one is your version?
Hmm, I must be mistaken then. Does Canada Post itself accept both units? If so, there should be an option to switch to/from metric from within the config.
Can you please elaborate on what you mean by this statement?
No problem, if a customer purchases an item for $10.00 and shipping price of $5.00, the total to be processed by the payment processor would be $15.00. If the fee were 3%, this would equal $0.45 with $0.15 generated from the shipping charge. Now, let's say you charge a flat handling fee of $1.00 in order to cover the processing fees. If a customers shipping ends up being over $33.33, then you will take a loss on the additional processing fee which has now become higher than your flat rate handling fee.
On the other end of the spectrum, if you charge a $5.00 handling fee to cover higher shipping costs, when a customer purchases an item that should only cost $5.00 to ship and now has to pay $10.00, you may now lose the sale.
My updated version allows the user to use either/both the flat rate or the percentage handling fee.
