If you have any sort of debts other than the school and house, pay them off! put an extra $50 a month to something until that's paid off. When you get a COL raise in January, put that extra 3% or so directly towards debt. Just think of your car payment and what you could do with that money every month!
As far as simplifying.
Go to low speed internet my cable connection is $20 a month for "lite" version compared to $45 for "high speed" and unless you watch a lot of youtube or download TV shows/movies from iTunes, you'll never notice the difference.
Drop your landline, and live off of your cell phones, just make sure you have enough minutes to cover you every months, and make sure you program your local PD into your contacts, 911 doesnt' always take you to your local PD.
Get movies from your library instead of Blockbuster.
Invest in memberships to the zoo, science museum, and a state park pass. For less than $150 a year we have something to do every weekend of the year. If the weather is horrible we go to the science museum. If it's iffy, the zoo, because we have lots of indoor exhibits to duck into. Absolutely gorgeous - parks. (I live in WNY too, we go the Niagara Falls with a state park pass)
Pack picnic lunches when going to the above activities, but do NOT run out and buy special food for the trips. It won't save you any money if you go buy a 6 pack of soda, bag of chips and deli sandwiches to take with you. Bake muffins, take fresh fruit and pack your own Tuna/ Egg Salad/ or PB&J. Buy reuseable bottles to take some coolaid, juice or milk from home. After lunch, rinse them out and fill at your nearest water fountain for the next "I'm thirsty" whine.
Pack your own snacks for when you're running errands if you're prone to stopping at the drive through donut place when hunger pangs strike. And make sure everyone has their water bottle before you walk out the door!
For Christmas, we cut the gifts down to 3 per child for our kids (plus stocking stuffers) and we request that family only gives one so as not to out-do mommy and daddy (or Santa if you go that route) We use the thought that Jesus only got 3 gifts, why should we receive more?
Make a list of your wants, and don't buy them until they have been on your list for at least 30 days, that gives you time to decide if it's really a need or a genuine want.
Make a list of things you will need soon, and watch clearance racks and sales for household items like pots and pans, linnens, etc. These things rarely go bust on you suddenly, so you can take your time to search for a deal.
Explore your local history. Take the kids on an extracurricular field trip.
We recently spent a whole weekend going out to an apple orchard, picking 2 busshels of apples, then we stopped at a berry farm, and picked 3 lbs of blueberries before we were rained out. The second day we spent washing and freezing blueberries and canning apple pie filling (still have 1 1/2 bushels to can)
Plant a garden with your kids. Quality time + free food!
Teach your kids how to sew using old clothes to make a scrap quilt. Again Quality time + a few small purchases (flannel can be used as a light batting for summer) = a warm bed in the winter.
