The price that displays in the configurator is the retail price. The dealer cost is displayed in an encoded form in the bottom-right corner of each product listing.
To decode the cost, ignore the first two digits and last two digits of the displayed code, and treat the last two of the remaining digits as decimal places.
In the cart, the encoded costs represent the item totals, not the per-item cost, so if there is more than one of a given item in the cart, the encoded cost in the cart will differ from that on the main product listing. The overall cart total is encoded in the same way, and is found below the retail total.
