Board and Card Games The sandman

Yeah i know this isnt a card game but there isnt a page for trading cards so i came here.

I have a question does anyone here collect the sandman series one cards - i got a factory sealed box off my girlfriend and am in desperation to find the final cards i need, sadly the cards i need are all rare.
if anyone knows a stockist online where i can get those cards standalone then i'd be very appreciative (ebay doesnt seem to be helpful today)
