I appreciate all the advice.... I dont buy or sell stock. my stuff is through a company that does all that for me.... I was more looking at what me as a homeowner and lower middle class income could do on a day to day basis....
Anything you can do to cut your expenses will help. The biggest expenses in most people's lives are food, car, and housing.
If you can bear to eat like you are in college you can save money by eating pasta, mac & cheese, lentils, and other assorted cheap foods. It doesn't give you a very good diet though. My SO does all the shopping and is religous with the coupons. Every couple of months she gets a shopping bag full of coupons from a friend of hers whose mother lives in a retirement community and gets the coupon flyers from the recycle bins (most people never even think to use coupons).
My S.O. saves LOTS of money by combining coupons and paying careful attention to sales - then using the coupons when the goods are on sale at the same time. She often gets her best scores on things like shampoo and similar goods. I have seen her come home with 15 bottles of shampoo and conditioner that she ended up paying something like $3.00 for after combining all the disounts. She also carries around little wallet thingy that is chock full of coupons.
If you go the coupon route see if you can hook up with other like minded people and share the coupons you don't use.
Check prices carefully - buying at places like Costco and BJ's is NOT always the cheapest price. You can often get better deals at supermarkets - especially with coupons.
I have seen numerous people waste huge amounts of money on automobiles over the years. By either buying cars that are way more expensive than they need - or buying cars that are just unreliable and eat up large wads of cash by needing constant repairs. I am an full on advocate of Hondas. I am on my third one (an Acura actually) and all three have been nothing but reliable. My last two were up at 185,000 miles when I stopped driving them. The first one I just wore it out by driving it hard (CRX). The second one was a 97 Honda Civic that was sold at 189,000 miles with NO rust on the body and was still in excellent operating condition. It probably had another 180,000 miles of life in it if the right person was behind the wheel. During the life of that Civic I replaced the battery once (at 160,000 miles) the brakes a couple of times in the front and once in the back, the exhaust system a couple of times, and a few other odds and ends. It was a VERY reliable car and was simple enough to fix yourself - which is by the way, another great way to save money - learn to do your own car repair. That car saved thousands of dollars in repairs over it's life over other comparable cars I have seen friends buy that have needed constant repairs of one sort or another.
Mow your own lawn (don't pay a service) - better yet look into doing "natural" landscaping that doesn't need as much maintainence.
Insulate the house better. Heating can run up huge bills depending on what type of house you have. Insulating a house that is poorly or completely uninsulated can pay huge dividends in heat savings.
If you are heating with oil you might find that by converting to gas you can save money - I think a lot of the gas companies give rebates if you convert.
Upgrade you heating system to a more efficient one - there are MA and Federal govt. rebates on some of this stuff.
Bring you lunch into work instead of buying it.
Get rid of cable TV or get basic if you have the expensive premium channels.
If you have kids make them do chores around the house, this will free up your time to spend on doing other things that save money (I see lots of people whose kids do nothing but suck up electricity playing video games)
Cruise yard sales - you would be surprised what people sell for cheap money or put out in the trash in the more expensive towns. The guy next door to me just put what looked like a perfectly good lawnmower out in front for the trash this morning - the trash guys didn't take it but some guy in a pickup stopped and picked it up. I remember the neighbor struggling with it because it ran like crap. I bet somebody who was good with small engines could get it running fine. Pick it for free - fix it up, then sell it for $100.00 on Craigslist. Easy money for the right person.
Frankly I think for the average person "investing" in goods that stand a good chance of gaining value is better than risking your money in the stock market. I have read a number of investment advisors that have pointed out that since the early 90's the average gain in the stock market has barely kept pace with the rise in the consumer price index. You could of course make a lot of money betting on the right stock - but that is a gamble.
