I cruise the eBay, but I have to say that I have not seen a single roll of the new Ektar 100 for sale...ever.
I think that the idea that most people who are asking for this film lack a film camera is not true (why, it is even nonsensical), since I chatted to a nice Kodak representative who gave me a few rolls. He was more taken aback that photographers were sharing the fact they could get free samples with other photographers, but he said it in the most polite manner. He was not upset, but simply astounded at the huge interest that this film drew and found that the stock of sample film would be exhausted in several week's time as opposed to six or nine months, as previously thought.
Regardless, Kodak has to give away all boxes marked "Sample," or throw them away. As long as photographers get to use this film, it behooves Kodak to get rid of it.
Now that I got my free film, I am supporting Kodak's generosity by buying 10 more rolls. I am sure that I shall buy much more than 10 rolls in the future (especially if released in 120 format!!!).
Happy shooting!
