Odd...
The msg I got from them a few days ago was only that the ap-15 were "oderable", not "in stock":

We are alerting you that the following product is now orderable at FrozenCPU.com.
This means that you can place your order now online and stock will be available soon.

And it said this on their site when I went to check out with some earlier today:

ATTENTION!! You have ordered some items that are not available for immediate shipment today.
These items are shown below and will be available soon (within 1-18 business days).
