I work as a financial analyst for a major corporation that sells products globally. I live and work in the US, their pricing model for the UK doesn't make any sense. It's like their FA just copied the US model and put the British Pound symbol after everything. There's no possible way the two would be $40 and £40 exactly. Especially since the base game was £40 to begin with in the UK. They probably just kept the pricing models the same as the base game lol, too much work to change it all for the DLC. I would be pissed if I were all of you.
