On the 'Product Detail' page is a table showing the availability of the product. All of these figures are Live real time stock levels.
For example, if the Minimum Quantity is 10, and the Order Multiple is 10, it means the product can be bought in multiples of 10. If you wanted 27 you would order 30 - the Minimum Order Quantity of 10 plus two additional Order Multiples of 10.
