Basically, vBucks are given out as a mission reward in one or two missions in one of the four main areas instead of the crafting material you would usually get. You have to have the required area unlocked and have the appropriate level requirements for the mission. Other than that, anyone can access them.
Here is the website I check after the store refresh each night to see if any missions have vBucks as a reward: https://www.stormshield.one/save-the-world
You should be able to get the 25 available in Stonewood if nothing else.
