 If you want to know how many items there are in your cart, you can use the `count()` method. This method will return the total number of items in the cart. So if you've added 2 books and 1 shirt, it will return 3 items.
 
 ```php

+You can also use the `InstanceIdentifier` Contract to extend a desired Model to assign / create a Cart instance for it. This also allows to directly set the global discount.
+```

 **N.B. Keep in mind that the cart stays in the last set instance for as long as you don't set a different one during script execution.**
