To add a PayPal “buy now” or donation button to your post, page, or sidebar, follow the steps below.
Keep in mind that if you want to add a PayPal button to a widgetized area like a sidebar or footer widget, you’ll need to copy the code into a Text Widget. Just click
the Text tab in your post editor and copy out the button code, and then paste
it into your Text Widget.
Here’s how to create the button:
1. Go to http://www.paypal.com/login and log in to your PayPal
account.(To access funds you receive through PayPal buttons,
you need a Premier or Business account.)
2. Click on Merchant
Services in the
main menu
