The “Want Ads” building is the best place in the game to earn Cents and XP easily.
Here are 3 major tips you need to know about it:
Firstly; you should be careful what you are going to sell, for example, an item require to unlock an area and instead of using it to extend your map you sold it. That means you will have to repeat actions to get it back, a second time.
Secondly, Fulfil the orders that require common items, even if you need them; it’s not really important because you can get them back easily.
Thirdly, when you don’t have one item required to complete it, switch the Ad by using the close button in the hope of getting an order with items that you have. A replacement Ad will appear in approximately 4 minutes.
