Shipping isn't working!

I have two plugins enabled Manual and Canada Post.. the sales that have gone through with the manual plugin have worked just fine but the ones that have to go with expedited (Canada Post) doesn't charge anything for shipping.

When I test it out it shows the expedited price correctly.. but when the sale goes through the shipping charge isn't added to the total amount.

What could this be due to??

Thanks!

Hi there,

I'm not sure I understand what's the problem. I just tried and the LetterMail - Canada shipping method is added to the total amount.
So is the problem about the Canada post method not showing (because I only see one shipping method) or is about something else?
To be sure, do you have a weight configured on every product and are you testing with a valid Canadian address?

Hi Eliot!

I just sent you a pm about this.. I'm hoping I've made myself clear.

When I test it from my end I can see the shipping too.. which is why it makes it really strange that I'm getting orders (2 now) that have $0.00 added for shipping. I don't have free shipping enabled.. and don't want to be offering free shipping.

I do have the weights configured, yes
