Food prices

While shifting some of my stuff, I happened upon a receipt from Nature's Northwest from 6/25/2001 (OK, it wasn't me that moved the stuff or happened upon it - it was Jolea). Since I've been feeling lately that the prices of food have been going up at a ridiculous rate, much faster than the growth in wages (what growth?), I thought it would be interesting to compare the prices. I was only able to find four matches, but it pretty much confirms what I've been feeling. Admittedly, four items isn't statistically significant in any way, but still, it doesn't contradict my impressions.

Bearitos Refried Beans: 2001, $1.29. 2008 $1.99.
Cascadian Farms Grape Juice: 2001, $2.99. 2008, $3.59.
Amy's Chili: 2001, $1.99. 2008, $2.79.
Tillamook Medium Cheddar: 2001, $2.99. 2008, $3.89.

70 cents, 60 cents, 80 cents, 90 cents. No big deal. Percentage-wise, though, around 70%, 20%, 40% and 30% respectively. I don't follow inflation, but those percentages seem pretty high. Everything just seems to be about 20% - 30% more expensive than I remember it being only a few years ago. Oil prices? Weak dollar? Stagflation? Come to think of it, why isn't Bush being tarred with stagflation the way Carter was? If this isn't stagflation, I don't what is (keep in mind it's very possible I really don't know what it is :) ).
