We have revised the way the Sale Price works. You can now add a sale price inside the chain (not only on the first role / the "retailer"). This will be reflected in two places:

• If you play a role with a Sale Price, Revenue will be generated for you whenever you ship a unit to your client.

• For your client, this price is seen as a Purchase Price (=> adds Cost), applied whenever he orders units to you.

Here is how it looks if a Sale Price of $10 is setup on the wholesaler:

By adding gradually-increasing sale prices on each role, you can simulate how value is added throughout the Supply Chain. At each stage, a profit is made if his sale price is higher than his purchase price. At the end, we can visualize where value is added inside the supply chain:

On the factory role - which doesn't have any supplier - you can now setup a production cost, added every week based on the quantity ordered for production.
