sundancekayak on "adding paypal button"

I'm adding a PayPal button to my website and ran into 2 problems:

1. Wordpress is inserting a box around the button. The Paypal code doesn't show any box.

2. I want the button to be on the same line as the price but at the end of the line versus right next to the price. How can I make this happen?
