OFFERING DISCOUNT
11. Offering a discount.

Paypal allows you to offer a discount.
- “Discount_amount” must be less than “amount”.
- If you don’t specify “discount_amount2″ then “discount_amount” will apply to all items not just the first.
- To use “discount_amount2″ you must specify “discount” as greater than or equal to 0.
You can specify “discount_rate” and “discount_rate2″ as an alternative to “discount_amount” and “discount_amount2″. This applies a percentage from 0 to 100.
Unlike “discount_amount” if you don’t specify “discount_rate2″ then “discount_rate” only applies to the first item.
Use “discount_num” to specify an upper limit on the number of items to which “discount_amount2″ or “discount_rate2″ applies.
Use the button creation tool wizard or this example code that provides a $0.15 discount on the first item ordered and a $0.20 discount on the next four items.
