#A This action is called if a user clicks any of the "Buy n books" dropdown buttons.
#B To isolate the CheckoutCookieService from the ASP.NET Core's HttpContext we have designed a BasketCookie that provides an interface that can be used in a unit test
#C The CheckoutCookieService is created, with the content of the current basket Cookie, or null if no basket Cookie currently exists
#D This method adds a new OrderLineItem entry to the CheckoutCookieService list of OrderLineItems
#E This statement encodes the list of OrderLineItems into a string, ready to go out in the updated basket Cookie
#F This method sets the basket cookie content to the encoded string
#G Finally we go to the Checkout page which shows the user the books, quantities and prices of the books they have in their basket
