Question about the store

Heya! Anyone know how the conversion rate works on the store? Just curious because I found today that all items on the store were raised by 1 or 2 dollars… image

(Oh also the 2nd image actually shows the aud price not the usd one because of a visual bug with the store)

That’s something we like to call inflation, all prices are converted from USD

I am aware of how the stock market and currencies work. However, I was wondering how often the store updates this because it seems as though it will change at indefinite intervals which is kind of frustrating because I was hoping for a semi-consistent price.

Still would like an answer to this
