Hey buddy, my stamps just arrived and damn, they're all Black! I mean, I had zero idea that they came in different sets, like I said, there was just absolutely no information about them, just a standard price per piece on the website of Austrian Post.
And no, unfortunately I ordered only 5 pieces. Not 5 sets. I probably would definitely have bought the entire set if they'd sold it like that! So strange or maybe when I translate to english or maybe it wasn't available to non Austrian customers...
Anyway, scroll all the way down to the page, look on the left hand side and see "Move Topic" to Economy == Collectibles. Good luck!
Sets werent made available to anyone. Distribution was always random. With only 1500 of the 150k total stamps being red, the chances are very slim you get one in a small order. With an order of 5 of them you only had a 5% chance of getting one in your order. I still haven't even recieved a dispatch email hope it comes soon
