Electric, water, and Gas, cutting the bill is frugal, green and I've been supposed to do all the stuff my whole life, lights and water off, fridge closed, unplug stuff, heat down, etc.

Phone I don't have/don't want all the neccessities of life, use the callerID on the cell, which we use so we can have a phone in pgh, not exactly a neccessity, but if we have to have a phone I prefer a cell. It doesn't ring and wake kids napping up, does keep track of who called, and can travel.

Cable net, ok pure luxury, but I do use it for email (keeping me off the phone) savings advice and parental reminders (helps to know most parents would gladdly trade their troubles for mine.

Some stuff can't be gotten rid of and can't change, my house, trust me no one is buying it, and needs sewage and waste, which is constant (well rising, but not cuttable by me)

So this leaves food. And that is a true sacrifice, not cutting out pop, DH's done that to a large degree, not cutting readymade snacks, been there done that, but everytime I have a glass of milk I think about the cost. OF MILK! I really don't want my kids growing up thinking we are so broke we can't eat, to broke for movies or eatingout maybe, but for MILK! Ugh. Bad enough we are to broke for steak, much less too broke for any beef. looking at the list of what we bought last week (when we spent double my prefered limit.) it had no real obvious 'fluff'

BBQ sauce, which the kids and DH have on all chicken, which is why they don't mind my lousy cooking,
cheese, which we use on everything,
laundry detergent, already the cheapest brand in the store, plus had a coupon.
Milk, three gallons, that is limiting them
Bread, two loaves, again that is limiting
yogurt, two cases, about two weeks worth, organic, for DDs digestive tract (ped recomended)
chocolate chips, used in trail mix and in DHs yogurt, cheaper than snack cakes
grapes, I really hate limiting fruit
bluberries, ok that is a splurge, expensive fruit there, kids love it
mushrooms, again splurge, but its a vegetable!
onion, again splurge, again vegetable
hot sauce, neccessary to get DH to eat ramen noodles (I did try to get him to switch to cyanne pepper, no luck)

some other stuff but you get the picture, not easly cut out.
