Shipping from Canada to US.After the US Supreme court decission, the rates calculated in Zonos and Stallion Express almost never match for me for the same HS Code. I have been playing chat and email tag with both but to no end, they don't explain why the difference, just argue the other calculation is wrong.So I can't be wrong. Either I am underpaying at Zonos or overpaying at Stallion Express.I don't track what tariff is for what, it gives me headaches.See examples. Every shipment like this. I go to checkout and that's what I pay when going to checkout.
