Hey there Odlex, we completely understand why there may be any confusion with this, we would gladly clear that up! This is a pre-authorization hold, so as soon as we can confirm that funds are available, we release the hold, returning it back to your bank!
You should be seeing the correct amount charged within a few days, we hope that cleared any confusion and answered your question!
Hello again @Odlex!
To answer your question, all charges are handled at your financial institution of choice. As every location has different methods of handling digital transactions, possible exchange rates, or limitations on purchases, we can't say for sure why a hold would be for any given amount. What we can say is that you'll be charged the price as reflected in your receipt of purchase.
We hope this answers your question!
