Is there a prize for buying carpets and wallpapers from Sahara?
Solution 1:
Sahara gives you a random carpet and wall every time you pay for her services.
If you like, it can be considered that her "prize" is an unorderable carpet/wall from her private collection; it is not always guaranteed you'll receive her own work... Sometimes you get cheap, commonly found carpet and wall.
Unfortunately, you could buy her carpets and walls every week, forever and what you receive will always be randomly chosen.
To clarify, there are no additional items or rewards you can receive from her, even once you've completed her collection.
