Hey I'm not sure if this was already mentioned but I could not find a post about it.
Basically what happens to me is when I'm checking the prices, I see a game that has a 20€ price tag and upon following the link to it's store page I see that the currency is sometimes different.
The number is always accurate. If it show's 20€ it will always be 20, but it can be either $20 USD, 20£ or 20€.
Although not a huge deal since the price range is pretty similar in all three cases, I thought I should post about it
and let you guys know since I wasn't able to find any mention of it.
