i just bought on official eset site should i contact the online chat in the work time? and what will be the price if i need to upgrade assume the price for 1 user is 10usd , 3 users is 25usd how much i need to pay for upgrading 3 users if i already bought 1 user license? or there is no standard answer and i need to discuss with the customer service?

just change my mind to have eset on more device seems can't find any clues or i must buy new license for more user?
