A kata to practice OOP principles

The following code belongs to an online shopping cart

Your job is to make the code able to handle the following business rules:

• add a promotional 2X1 discount for every product but any snack
• for each bundle of 1 shampoo and 1 soap you get another free soap
• when you buy 2 bags of nachos or more you get 1 dip for free
• for each bundle of 1 soda and 1 bag of chips, you get another bag of chips for free

restrictions:

• no more than 5 lines per method
• no getters/setters

Please apply the OOP tenets: Encapsulation, Polymorphism, Abstraction and Inheritance as you see fit to make this code object oriented
