On the Shop window, you have the possibility to buy special offers using Diamonds or Nutaku Gold. Special offers give you the best value. You can browse through the offers by using the two arrows at the bottom of the page.

You can also purchase consumables for your Stars in the Shop. Select one of the four buttons at the top of the screen (Happiness, Lust, Attraction, or Energy) and pick the item that you want to purchase, and then select the desired amount.

The last button is for purchasing Cash or Diamonds.
