I've noticed a slight increase along with almost everything else.
The drastic changes have been with some very popular brands, Balvenie and Highland Park come to mind, 2 of my favorites, seem to have catipulted their prices due to repositioning the "premium" market or awards won, which I see as shooting theirselves in the foot. I buy less of them now. Others have gone up due to availability so as to stretch their stock, but I can see that reasoning. All business, I'm sure, but not good news for the consumer. To me Macallan have priced theirselves out of the market, at least mine and I'm starting to narrow my purchases to reasonable favorites and new releases. My exceptions are the top end malts like the Talisker 20 & 25, Glenfarclas 25, Glenrothes '74, and even Balvenie 21, which were expensive, but worth every penny. Everything in perspective, you know.
