So sorry you lost all your boosters. Sadly that happens when we need to reinstall our game for whatever reason. I know you can earn more boosters soon if you just keep playing. Good luck and have fun.
The piggy bank is a feature that could be changed at anytime but for now they just keep filling if you buy them. I never buy mine so I can't tell you much more. Have fun crushing. Sorry don't know the answer about your shipping. This community does not deal with purchases.
