"Decarz, it states only a few cans left, looks like they have decided to stop selling it on amazon."
As far as anyone knows, DNA has never been selling on Amazon.
That is likely one of the posters here on iHub. He reported several months ago that he had bought some cans of DNA and then put them up for sale on Amazon for a ridiculous markup. He said that he sells all kinds of things on Amazon with such a markup because people in remote parts of the world will pay extra to get stuff they want shipped to them when it is difficult to get it shipped there via other means.
