Prices in the webstore

I am trying to purchase the maul light speed bundle on the webstore, however the prices are shown to me in euro's 

The maul Bundle is 39 US dollars, in euro's the price is 47, 95 euro, this comes down to almost 54 dollars..notice the difference? (Currently 1 euro converts to 1, 13 US dollar)

Why does everything show up en English on the webstore except the prices?

I do not , have not and will not ever use a vpn

Problem 2 is whenever I try to enter the expiration date of my creditcard  it gets changed  into a mathematical fracture for example 01/29 instead of 01 / 29  this is a debilitating error... The problem is clearly on the webstore only as any other website doesn't have this problem

I'm afraid by the time this issue is solved it will be Christmas 2025
