Adding on to your excellent point, which tax configuration do you use for calculating the tax? If the affiliate is what causes nexus, do you use the affiliates local tax rates for calculating tax obligation or do you use the customer's local tax rates for calculating tax obligation? It seems absurd to me that I would pay more in taxes if I click on a link from Alice's website than I would if I were linked to the same product on Bob's website.
