I really love my Garmin Forerunner 305. While I don't feel they are necessary for a good running workout, it's very nice to be able to track my speed and my distance. I find it very motivating! It also has a marker function that tells me what direction to run in to get home if I get lost!
I'm usually very leery of anything I've seen over-hyped on TV, but I picked up some of these up anyway because I thought they'd be nice for my purse for an emergency hunger situation. I was pleasantly surprised with the Red Raspberry's taste and it did leave me feeling satisfied!
Carrying a healthy snack is a great idea, but make sure it's durable! That banana you stuck in your purse this morning will not help you avoid the candy bar after lunch if it is disgusting mush; the granola bar will not help you avoid the drive-thru if it is crumbs from its ride in your backpack!
Store brands are often very good, so give them a try! This is especially true of things like frozen fruits and veggies, staples like flour and milk, and cleaning products, where the taste or use doesn't vary much between brands anyway.
Know what your needs are when you are buying a major appliance or a car. Find out what features you need. Make sure you have them, and DON'T LET ANYONE TALK YOU INTO ADDING ON NEAT FEATURES YOU WILL NOT USE. It isn't worth the extra money for useless (to you) features that sound cool in the store!
When you move or your contract is up, investigate what your options are for services like cable. Find all available providers. Check their internet prices, then call for a phone quote (often they are different.) Tell them about deals you've seen; often they will then offer to match or beat it.
I use a Misto sprayer instead of cooking spray. It's really good for giving veggies a light olive oil glaze for roasting, spraying a light mist of oil on salad or meat, and spraying my pans before I stir fry. You know you're using a good quality oil, because you pick it and fill it yourself!
