This module hooks into a few different parts of Ubercart to allow store administrators to associate a fee or discount with payment methods.

Code

function uc_pma_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == 'uc_payment_methods_form') {
    $form['methods_info']['#value'] .= '<div>' . t('The adjustment field can be used to associate a fee or discount with a payment method.  Specify a value that is a flat amount or a percentage of the subtotal to be added or subtracted when a payment method is chosen at checkout. Examples: 3%, 1.00, -5.5%, -2') . '</div><br />';
