I believe standalone VFP boxes are no longer available from Microsoft. How long from inidivdual vendors will vary from vendor to vendor as their inventories and sales will be different. You can still get VFP as part of an MSDN subscription.

>A colleague asked me how long VFP 9 will be available for purchase, either directly from Microsoft or from other vendors, after 'mainstream supports and after 'extended support' ends. Obviously I have my own copy, but my colleague and I need to be able to tell new clients what their options are with respect to purchasing VFP, now, and in the future.
