Overview

• Acme Widget Co are the leading provider of made up widgets and they’ve contracted you to create a proof of concept for their new sales system.

• They sell three products:

• • Red Widget (Product Code: R01) - $32.95
• • Green Widget (Product Code: G01) - $24.95
• • Blue Widget (Product Code: B01) - $7.95

• To incentivise customers to spend more, delivery costs are reduced based on the amount spent. Orders under $50 cost $4.95. For orders under $90, delivery costs $2.95. Orders of $90 or more have free delivery.

• They are also experimenting with special offers. The initial offer will be “buy one red widget, get the second half price”

• Your job is to implement the basket which needs to have the following interface

• • It is initialised with the product catalogue, delivery charge rules, and offers (the format of how these are passed it up to you)
• • It has an add method that takes the product code as a parameter.
• • It has a total method that returns the total cost of the basket, taking into account the delivery and offer rules.
