[mihaijoldis]

Based ona customer's requirement.
If a user purchases a Pass (AA, recurring) they are charged a signup fee. The next time they wish to purchase it they should not be charged the signup fee:

function edd_remove_signup_fee_if_purchased( $item ) {

	if ( ! is_user_logged_in() ) {
		return $item;
	}

	// Change your Membership ID here for which you wish to remove the Signup Fee.
	$excluded_download = 405;

	if ( $excluded_download != $item['id'] ) {
		return $item;
	}

	if ( isset( $item['options']['recurring']['signup_fee'] ) ) {

		if( edd_has_user_purchased( get_current_user_id(), $item['id'] ) ) {
			$item['options']['recurring']['signup_fee'] = 0;
		}
	}

	return $item;
}
