There's no reason these days that when an order is placed, that the database gets updated to reflect an order. So when the website goes to query this database, it will show the correct numbers most of the time. But if you happen to hit the website when there is stock and stock is no longer available by the time you go to place the order, the site can then tell you they are out. It is not a good idea these days to manual systems.

Take Best Buy for example. If you order something from them for in-store pickup and the site tells you the sotre you want to get it from has it in stock, yet when the staff go to actually find it, they don't have it, best Buy will ship the item to you with free shipping. This happened to us once with a window air conditioner. And Best Buy did make good on their free shipping.
