Inflation here? gas/grocery prices just continue to climb

So I've noticed that over the last few weeks, the gas prices came down a bit, stayed around the same price, and are now slowly creeping up again. I couple gas stations I cross on the way to work were at 3.85 while most other places were ten cents cheaper. Well, they crept up to 3.89 last week and today I saw they're up to 3.95. Sigh.
