Remove Extra Registration Steps

Hello, is there a way to lessen the steps on member registration? As of the moment there is the:

STEP 1: Choose your subscription Method
STEP 2: Enter your registration details
STEP 3: An extra page with the product amount and a coupon code at the bottom
STEP 4: Paypal Redirect

Is there a way to skip the step 3 and direct to the paypal page after the registration? thank you very much
