Big Chooser for osCommerce is product based discounting. Buy multiple items, get a discount on other products or combinations of products, or receive other products or combinations of products free. OSC_PAYMENT
Big Chooser is configured using a series of PHP commands in a special purpose language designed for creating discounts. Because of this, while it is powerful and completely configurable, it is really intended for developers customizing sites for their clients, not for store owners with no programming background. If you are a storeowner, Discount Chooser may be a better option for you.
