Personally, not really a whole lot as my new suv gets better gas mileage than my old suv, so really I'm just back to paying what I was, which isn't a big deal for me.
For our business, the high costs of materials, like steel, copper, aluminum, ect, is having more of an effect. It's getting to be very expensive to put up a new building. In fact, the high price of materials has made a lot of guys I know put projects aside. Even our fuel delivery guy said he isn't selling anywhere near as much fuel oil as he used to, not just because of high fuel prices, but because there are fewer construction projects going on. (Which I'm hoping will mean a surplus of fuel oil, causing the price to drop.)
