Yes that's the stuff, Kev. Seller is honest enough to say it is well beyond it's expiry date but was OK when last used 5 years ago and has been stored at freezer temp of -18 ever since bought.
His claim however that Kodak says that the life of this RA4 paper at that storage temp is indefinite might be questionable. I could find nothing in the Kodak link the seller provides to establish this assertion The Kodak publication only speaks of thawing time at this temp.
Maybe some Kodak RA4 experts will respond. If there is a good chance that very low temp storage means that there is another year or more of life left in the paper then it might be a reasonable buy.
Personally I liked Supra III.
