Yeah. Even when thinking about getting stuff shipped from Amazon I feel this way. UPS/FedEx are really efficient - they have to be. I mean, they choose their routes based on what will use the least gasoline! They have advanced software meant to save them money by limiting distances traveled, gasoline, trucks and labor used, etc. If I drive to Target, the goods still need to get to the Target in the first place and my driving isn't going to be as good as UPS'.

I really try to cut down on the easy things. Getting rid of single serving containers from the supermarket, reusing containers, etc. A nalgene is a bottle just like the bottle of bottled water. While an environmental scientist might be able to calculate out precisely what Netflix and Blockbuster use, there are some no-brainers that most people don't do - like turning the thermostat down and putting on some nice wool socks. Plus, I'm cheap and those energy/waste savers also tend to save money!
