- ===================
- Offers and vouchers
- ===================
-
- The ``oscar.offers`` app offers functionality for basket-level offers and vouchers. This covers
- features such as:
-
- * 3 for 2 offers on fiction books
- * Buy one book, get a DVD for half price
- * A Christmas voucher code that gives 25% off all products until Decmember 25th
- * All students get £5 off their first order
- * Visitors coming from an affiliate site get 10% off their order
-
- In short, it is very flexible.
-
- Conditional offers
- ------------------
- A conditional offer is defined by two things:
-
- * A *Condition*, which is some criteria that the user's basket has to have met. These are
- either count- (eg must contain one fiction book) or value-based (eg must contain £10 or more
- of DVDs).
- * A *Benefit*, which is the discount that is applied to the basket.
-
- When an offer is applied the basket, the products that are used to meet the condition, and the
- products discounted by the benefit are "consumed" so that they are not available for other offers.
-
- Vouchers
- --------
- A voucher is essentially a code which links through to a set of offers.
