Bear in mind that most European operators of A300Fs are now dumping them (eg Schreiner, Farner) due to DHL and other contractors using their own rather than contracted aircraft. The A300F has not been as good a freighter as the publicity documentation made things out to be - providing a payload only slightly more than that of a DC8 or B707 (although with greater volumetric capability) and at the end of the day I suspect that a lot of the owners - especially CS-Aviation will end up with aircraft they will be hard-pushed to dispose of except for very low prices.
Interestingly, there has been little interest in the A300F from the main operating area of DC8s and 707s - Africa.
