For stuff like this that is free (or almost free) at CC, you really should check their online site for stock before going to the store, and probably even place the online order to ensure that they have one for you when you get there. In my case, 2 of the 3 stores on my list (as well as direct ship) show it as being out of stock. Fortunately, the 3rd store claims to have it, so I placed an order yesterday and my wife is hopefully picked it up about 30 minutes ago (I assume she did, I would have heard from her if they didn't have it in stock). They still claim to have it available according to their website.
