I have two non used Prograde CF Express B, 256GB, Gold for my future Nikon Z9 which is still on the waiting list. I am considering to spend more to buy Prograde CF Express B, 325GB, Cobalt if the gold version one(s) can be sold. Asking prices:

For one, $250
For two, $480
Payment: check or ACH. Shipping to 48 US continental states included.

Thanks!
