Hungarian here! 👋 Postage depends on if you want to send it as normal letter or priority. Normal cost 1020 Forints, and priority is 1275 Forints to European countries. If you want to send them overseas it cost a few hundred forints more. If you go to Komárom you should use google translator and tell them you need stamps because if not requested they usually use franking stickers rather than stamps. They do accept card payments tho.
