Here are a few of my tricks: Shop at ebay for some of the stuff you like to use. I get a lot of my mid to higher end beauty supplies from there at low end prices.
During the summer months you can save a lot of money buying from a local farmer's market. Better, healthier food that's cheaper. You just can't go wrong there. Check with your Chamber of Commerce to see if there's one in your area. You can also check localharvest.org to see if they have one listed for your area.
Invest in your own small vegetable garden at home too. It's fun, it's relaxing and it's a great learning experience for kids too. Also, learn how to can and likewise invest in some canning supplies. You can often find used canning supplies at flea markets or antique shops. Also invest in a juicer. Juicing my own fruits and vegetables helped me to make sure that I was buying only what I needed and not what merely looked yummy on the shelf. I save money too.
Stop buying so many different kinds of cleaners. I'm not really sure how much money I save by using old fashioned - and environmentally friendly - ingredients. Because I've been doing it for years. Vinegar is your new best friend. Baking Soda is a close second. 20 Mule Team Borax is another favorite of mine. For reference and full on tips check out the book "Organic Housekeeping" by Ellen Sandbeck.
Before getting involved in ANY network marketing, direct sales, multi level marketing, whatever else they call themselves, do extensive internet research. Most of them don't work unless you already have plenty of money to spend, and no one trying to sponsor you will want to even hear about "market saturation" much less give you a straight answer about it.
I do work out of my home, and I've found a way to make some money at it. If you want to know how, just message me back. And no, it's not selling drugs.
Angel Food Ministries is great. I use them pretty frequently. If you have a Homeland, shop there, get their Homeland One Card and use coupons. Also, if you have Aldis they are great for canned goods, meat, boxed foods and all sorts of things. The only catch there is that you pay cash - something I rarely carry. But Aldis may be best for you because of that: You have to keep within your pre-set limit.
Goodwill, other thrift stores and consignment shops are great. My faves for that are consignment shops though. I happen to be petite and so I also shop from Delias.com quite a lot. Their clothes are inexpensive to begin with and their sale prices are great. Same with LaRedoute.com. Again, check out Ebay for clothes too. You'd be surprised what you can find. You might also invest in a sewing machine but only if you're inclined to sit and sew. I can't do it. Just can't, but I admire people who do! But growing up, my Mom made a lot of our clothes as a way to save money. If you go this route, don't be afraid to be creative and jazz up old clothes or recycle them into something else.
I didn't like coolsavings.com myself. I found that I had to give too much of my private information out, too often in order to save on stuff I don't buy anyway.
Get on WIC. Generally, unless you're loaded, you qualify for WIC. If either you or your hubby are Indian and can get an Indian card, do it. My hubby and daughter are card carrying Osage and there are some great benefits in that. First Nation Tribes are generally pretty good about supporting each other. It's some of their fundamental beliefs.
For fun and entertainment: invest in a deck of playing cards (and if necessary a book of card games). You, your husband and friends can have lots of fun actually getting to know each other better while you chat over cards. Likewise for some other board games and the like. Have small gatherings with different people regularly and make it potluck - another good way to save on food. For your whole family, be on the look out for community sponsored events - summer is a great time for that. Also, if you check out localharvest.org you'll find that some of your area farms offer tours and activities geared for little ones. Browse around.
Now, this might be hard but find a way to save money. Check with your local bank to see if they have an investment counselor that can help you establish an IRA. See what the minimum opening amount is (plus fees) and save for it. If you're interested in Socially Responsible Investment check out paxworld.com or domini.com. Being low income I am very interested in Socially Responsible Investment because I figure I might not be so low-income if more people believed in being Socially Responsible. Also check out your states college savings plan. If you live here in Oklahoma the website is ok4saving.org. It's important.
