Double Rewards has started! 
Remember
Using your Generous Customer Booster
will work with this event

Generous Customer Booster only doubles our base value of a helicopter order. It does not include factory upgrade amounts.
Double rewards doubles the total amount.
Example: Your helicopter order is worth 600 coins. This will include any extra percentage from your factory upgrades. Generous Customer Booster will ignore the extra from factory upgrades and only double your base value of the order. So this may be 500 coins (
this is just an example, it will depend on how big your factory upgrades are). Bringing the total to 1100 coins.
Then Double Rewards will double that making your total 2200 coins. So it is still well worth using your Generous Customer Booster
