I don’t want a free trial in the Vacation app, I’d rather buy Sago Mini Vacation right now.
Not a problem! To buy Vacation before your free 7-day trial ends, enter the game, then tap the banner that appears at the top of the screen. The banner will disappear after a few moments, but you can always bring it back by exiting the game and then re-entering it. On the offer screen, select “Vacation: One time purchase” to buy the standalone game.
