I've been watching the price of Power Service going up over the last couple of years. But the thing that really surprised me is that the jug has also shrunk by 16oz. For years the price was consistently about $17 for an 80oz jug. For me that was 5 doses at about $3.63 per dose. But the price has climbed to $20+ for a jug, and I'm only getting 4 doses out of it. I'm guessing that this isn't going to stop, either. I wouldn't be surprised if in the near future they will drop the jug and be selling those 32oz bottles for $20.
