The Export HQ is exclusive to regions and there is 1 per region. They are the most efficient way to earn regional Simoleons. The Export HQ is unlocked when the population in that region reaches 500. The Export HQ opens and closes every 1-4 days. It is open for 24 hours before closing again. While it is open you can start a shipment which is how you earn regional Simoleons. Each shipment has 3 rows with 3 random items giving a certain amount of regional Simoleons and a bonus for getting all 3 items in the row. After completing the 3 rows the truck will leave and a new one will come in 2 hours. This can be sped up by Simcash or watching an ad. Each truck stays for 6 hours before leaving. If a truck is still there when the Export HQ closes it will go into overtime which means once that truck leaves or you finish the rows the Export HQ will close. When a shipment is started 3 floating pig balloons appear on it. These represent the remaining piggy banks. Every time the player finishes 3 rows with a max of 9 a piggy bank balloon will float away into the sky.
Piggy Banks
There are 3 piggy banks per Export HQ. The first piggy bank is pink and gives 2,000 regional Simoleons. It requires 3 rows to be done in the Export HQ to be unlocked and can then be purchased for $2.99. The second piggy bank is beige and gives 4,000 regional Simoleons. It requires 6 rows to be done in the Export HQ and can then be purchased for $2.99. The third and final piggy bank is yellow and gives 8,000 regional Simoleons. It requires 9 rows to be done in the Export HQ and can then be purchased for $2.99. After the Export HQ closes you can still purchase the piggy banks you unlocked until it opens again.
