If you transfer money from one bank account to another bank account it can be pricey, especially depending on the amount of money.
Don’t forget that if you send money to another country, there might be different currencies and different exchange rates, that may result in a different amount of money being delivered to the addressee.

“No matter where you are, you can get your money in an instance”. This is a general slogan for every relevant marketing campaign. Does it work in real life? Not always.
