I am learning how to navigate through Magento; there is definitely a learning curve and I've not be exposed to this much abstraction before. Overall, it's been tough but a good experience.
My question is how to get the tax RATE on an invoice or order. I do not want to get the tax amount, but rather the rate.
I'm thinking this is associated with the shipping address. My company's orders have only one shipping address and all items are associated to the one shipping address. How would I get this?
