(Hey Bob...I don't think you're getting 70 mpg on 600cc.) (Speee...I also don't think you can go 200 mph on 600cc.) But, my Trek gets great mpg's. Of course, it won't do anywhere near 200 mph; not uphill, anyways.
That's just it. Most people don't take the time to actually go out of their way and comparison shop. They take those prices at face value, never looking for stuff on sale OR finding a cheaper place to shop. I can find the exact same items at 50-60% off if I choose to go to other supermarkets...of course there are legions of people who have no idea that they can find the same items cheaper. Of course, the giants such as Kraft, General Mills, etc, etc depend upon people's consumption habits. I get the feeling that with the 46 million and growing with SNAP cards, there's alot less people buying all the name brand products.
