Seriously, I was getting RWT at $30-35 ten years ago, inflation has not tripled prices. Each to their own but I can think of wines $30-$50 better than RWT. Don't get me wrong, it's a very nice wine but what it isn't is a great wine and that's what I want for close to $100.To add to this I have picked up RWT 2015 (?) at sub-$100 prices through CM, which is a very appropriate price.
RRPs are a stretch for Penfolds, but hardly alone in this regard; consider Grant Burge Meshach/Shadrach for example. Plenty of wineries going down this route to try and segment the market a little bit. IMO it's distasteful and perhaps a bit short-sighted as consumers move to better value wines due to intimidating (but rarely realised) RRPs.
However, their top end wines are still fantastic, often exemplary, all the grimy sales tactics in the world doesn't change that.
