Not tested but try experimenting by removing the RETURN.

Code:

    static function display_price( $oprice, $user_no ) {
        if( !empty( $oprice ) ) {
            $prices = self::get_available_prices( $oprice, $user_no );

            echo '<strong>'.CURRENCY.number_format( $prices[ 'price' ], 2 ).'</strong>';

            echo '<br/><br/>';

            if( $prices[ 'charge_out' ] > 0 )
                echo 'Suggested selling price:<strong>'.CURRENCY.number_format( $prices[ 'charge_out' ], 2 ).'</strong><br/><br/>';

            //return $prices[ 'price' ];
        }

        echo '<strong>'.CURRENCY.number_format( 0, 2 ).'</strong>';

        return $oprice;
    }

or

Code:

    static function display_price( $oprice, $user_no ) {
        if( !empty( $oprice ) ) {
            $prices = self::get_available_prices( $oprice, $user_no );

            echo '<strong>'.CURRENCY.number_format( $prices[ 'price' ], 2 ).'</strong>';

            echo '<br/><br/>';

            if( $prices[ 'charge_out' ] > 0 )
                echo 'Suggested selling price:<strong>'.CURRENCY.number_format( $prices[ 'charge_out' ], 2 ).'</strong><br/><br/>';

            return $prices[ 'price' ];
        }

        echo '<strong>'.CURRENCY.number_format( 0, 2 ).'</strong>';

        //return $oprice;
    }

Try it.
It's not easy to debug the codes without seeing the actual live result.
But let me know the output.
