I've really cut down on running to the grocery for 1-2 items. Since it's almost all mountain driving to get there and back, it's approx $4.50 just in gas (maybe more - my math sucks). I used to run up to grab a gallon of milk or one of another item, but no more. I probably go once every 1.5 weeks instead of the once every couple of days I used to go.
I get to go to Atlanta tomorrow though which means I have an excuse to do a Trader Joes run

Taking 3 coolers.
