PayPal does not support discount or coupon codes.
You can also use a script to apply a discount to that amount and then transfer that reduced amount to PayPal as a deferred amount. The following sample script provides discounts for all prices. Once set up, you can activate or deactivate the discount by changing the line of code.
To generate a discount button code:
Log in to your PayPal account.
Click the PayPal button.
Click the Choose a Preferred Button Type button.
Enter your details to customize the knob to suit your needs.
Click Step 2: Track Inventory, Profits and Losses, and deselect the Save to PayPal button. (This will ensure that you create a button that is not hosted.)
Click the Create button.
Click Remove Code Protection. (You will need to do this so that your code is editable.)
Click Select Code to select a button code.
Copy the button code and paste it into your own web page code.
discnt = 10; // set blanket 10% discount
