Google has started a new web site that gathers all sorts of advice for saving money, called Tip Jar.

The suggestions come from readers and frugal-living websites. People can contribute their own ideas and vote on their favorites from other people. You might have heard some of these ideas before -- use the public library, shift to CFL lights, etc. -- but others might be useful and new.

Here's a random selection of tips.

"Drive your car longer. The buy new versus used debate often overlooks the most important factor–how long you own your car. Drive it as long as you safely can for substantial savings."

"Simulate a Low Flush Toilet: If you don't have a new, water-saver toilet, you can simulate one by putting a clean brick, or a sealed plastic bottle filled with pebbles, or a weighted mason jar, into your toilet tank."

"Use Power Strips: Even in sleep mode, your computer, DVD player, and other electronic devices use some energy. By plugging them into power strips, and then turning off the power at the strip, you use less electricity."

"Stay married. Divorce will wreck your finances and your spouse’s finances."

"Master the thirty day rule. Whenever you’re considering making an unnecessary purchase, wait thirty days and then ask yourself if you still want that item."

There's a lot more at the web site, here.

What advice would you put in the Tip Jar?
