I hav ewondered about this too: when I came across some DK Fuels in a store at a good price, I snacthed them up. I turned around and sold one "NIB", but I had sprayed it 3 or 4 times, just to make sure it wasnt filled with water or any of those horrorstories you hear with sought-after discontinueds. The buyer didn't complain, but I probably would have been just as suspicious as you, georgiatechboy, had I been on the other end of the transaction. Is this unethical? Should I have billed it as "99.9% full, tested once" rather than "NIB"?
