Implement the code for a supermarket checkout that calculates the total price of a number of items placed into a basket. Goods are priced individually, however there are weekly special offers for when multiple items are bought. For example “Apples are 50 each or 3 for 130”.
Weekly offers change frequently.
| SKU | Unit Price | Special Offer |
|---|---|---|
| A99 | 50 | 3 for 130 |
| B15 | 30 | 2 for 45 |
| C40 | 60 | |
| T34 | 99 |
The checkout accepts the items in any order, so that if we scan a pack of Biscuits (B15), an apple (A99) and another pack of biscuits, we’ll recognise two packs of biscuits and apply the discount of 2 for 45.
Please fork this repo and implement the above requirements spending no more than 60 minutes. When you've done that please send the url of your solution to your representative..
