Tip Jar allows you to post your most tried and true tips about saving money while traveling, babysitting, or commuting, and share them with the world. Have a tip about how to get the best rates when traveling abroad? Or perhaps how to entertain your kids on a dime? Leave it in the Tip Jar, and get plenty of free tips in return. Personally, the one about never grocery shopping on an empty stomach really hits home with me. I always put junk in my cart I don't need just because I'm feeling ravenous, and end up spending more than I should. See? Already helpful.
