WHY Showing USD in listing but in checkout Sold in EURO

Hello; How are you? Today, I was very determined to upgrade my Cubase 10.5 software to version 13. And I see it on the update page as 199 USD. However, when I select it to purchase, it changes to 199 EURO. I live in Turkey and these two currencies are very different in value. Euro is more expensive than USD and I want to know why. I’ve given up on updating for now. Maybe I’ll do it if there’s a 50% discount.
