1) Moving Trucks - While shopping around for the greatest deal on moving trucks, I found that Budget Rental charges per day, while U-Haul charges per 24-hours. So, if you need a truck on Friday and Saturday, U-Haul is definitely the cheapest option by 50%. However, if you need a rental for one day only, you may be able to find coupon codes online to save 15% on a Budget truck rental. The only drawback is that you have to pick up and return the truck by the rental stores hours. Some have limited hours which may end up causing you to return the truck late and get charged an extra day.
If you want to comparison shop for the best deal on either moving yourself OR having a moving company move you, you may want to try this site.
2) Utilities - The second resource I found is another comparison site, where you can compare the companies who offer utilities in your area. You can find the best deals on phone service, internet service, gas, water companies, etc... I visited whitefence and found our new phone and internet service through Verizon, and because of this site, I found out that I qualified for a new Compaq mini netbook for FREE with my new service!
Even if you are not moving, you can still "shop around" for the best deals in your area. I hope this helps you a little too!
