My general lifestyle has always been in line with money savings, so when things in the economy took a turn for the worse, I really didn't have to change much.
Things I did to help save money a long time ago was cutting myself off, so to speak, with spending. I found what my needs were and my favorite wants. I made sure that with a little extra "mad money" allowance was put in my checking register with my paycheck, and everything else got auto-transferred to savings. Since I never put my full paycheck amount in my checkbook, I mentally think that's all I have to spend, and if I need to dig into savings for something - that's harder to justify. If I left that money in my checking account, it would be spent. That alone helps to psych yourself into spending less money.
Recently I've had the opportunity to start a garden. Hopefully in time I'll get good at growing a garden which will help save on produce (especially once I learn how to preserve the foods).
Last summer I stopped buying bread and started making my own at a fraction of the cost. I just couldn't justify spending $3 a loaf. With the electricity included, I think each loaf now costs me about $1.40, plus my house smells sooo good when I bake a new batch every 3 weeks or so. I'm now looking into other baked goods that I can make that would save the cost of buying.
For meat, I save up Omaha Steak gift cards I get on survey sites and wait for fantastic sales they have and stock up (plus there's the FC Shopping rebate to boot). Either that or I'll go to a couple local butchers which sell higher quality meat at cheaper prices.
Recently I started researching gift card sales sites. I use a site called Gift Card Granny which is a router site for several sites that sell and buy gift cards. Using them you can buy gift cards for several vendors that others don't need anymore at a discount. Spending $22.50 on a $25 gift card for a place you frequently shop - you just saved $2.50. Also, if you have gift cards you'll never use, instead of throwing them away, consider selling them to one of those sites. Gift Card Granny also shows the percentage paid for gift cards sold by the various vendors, so you can sell your partially used card to the vendor paying the highest percentage (you have a $19 left on a card, and a site will pay you $15 to sell it to someone else - not bad).
A tip if you are interested in the gift card sales sites - I just noticed that FusionCash is now offering 0.4% cash back when you buy gift cards with balances over $20 on national brands at Raise.com (check out the FusionCash Mall under Gift Cards). So if you find a good deal on their site, you'll get a little extra back at FC too - win-win.
