I’m happy reading this as I’ve just logged in and was devastated to see the price increase. I’ve been saving for some time for a membership, got a 30 day trial and bought a NUC just for Roon ROCK, I’m in love with the product. Logged in to check my finish date and take the plunge and saw the increase so thank you so much for honouring it, I won’t lie I would have had to walk away 
Now I just need to read the full thread on how to purchase !
