That's right! At the start of each new day you’ll receive three Gift Boxes that can be used at any merchant. As you start leveling up the amount of Merchant Gift Boxes you get will increase.
You ran out of Gift Boxes and you want more ?
-Just tap on the Gift Box icon and use your coins to get more.
Can I save my Gift Boxes and use them for tomorrow?
-Sadly no, your Gift Boxes disappear at the end of each day. But there’s always tomorrow! Each day you'll start with 3 new Gift Boxes.
