Answer 1

I believe each product has a price. To that start with relating PRODUCT table to PRICE.
In cake this is done very easily:
in your Model (Product.php)
class Product extends AppModel{
public $hasMany = array('Price');
}
in Price.php
class Price extends AppModel{
public $hasBelongTo = array('Product');
}
in your controller if you query any of these Models the returned array will contain data from both models.

Answer 2

make the relationships as follow
Product.php
....
public $hasMany = array(
'Price' => array(
'className' => 'Price',
'foreignKey' => 'product_id',
'dependent' => true,
'conditions' => '',
'group' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
),
....
Price.php
.....
public $belongsTo = array(
'Product' => array(
'className' => 'Product',
'foreignKey' => 'product_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
....
then in your controller use this query
$this->Product->find('all',array('contain'=>array('Price')));
