Umm, which country has the biggest population? ¯\(°_o)/¯ idunnolol
Does Klarna enforce that the `purchase_country` is one of its supported countries NO, FI, or SE?? If not, could a shop not be can be in US, but be using Klarna because it sells to a country Klarna supports and uses that gateway. If we raise here, customers would never be able to make a purchase on this shop. (Also, isn't `purchase_country` supposed to be where the purchase is being made, not the merchants country likes its been set?)
