Here's one link that gives some rather good advice using the 'net as a tool:

And a couple of ideas from the link:
"1. That SUV of yours seemed like a good idea at the time, but now you're paying way too much to fill 'er up.
Solution: First, look for the cheapest gas prices in your area before you head for the pump -- they may vary by as much as 20 percent within a few blocks and can change frequently.
Gasbuddy.com collects price information for the U.S. and Canada from 173 websites.
Gaspricewatch.com collects prices on 128,000 gas stations from 123,000 volunteer spotters.
Be careful about how you use debit and credit cards to pay for the gas. Sure, gas company credit cards offer rebates on gas, usually from one to five percent. But they often carry high annual percentage rates and limit you to a particular brand of gas. Some even offer teaser rebates of up to ten percent, which may be available for only 30 days. A better choice is a general-purpose credit card, with rebates wherever you buy gas.
Avoid using your debit card. When you buy gas on a debit card, your bank "locks up" as much as $100 for as long as several days or until the station owner processes the transactions. If your bank account is running low, you may bounce a check or two.
An easy way to save on gas? Properly inflated tires. Check them weekly and shave up to 9 cents off a $3 gallon.
2. You stop at the supermarket a few times a week to pick up something for dinner, tossing in pricey items as you go.
Solution: Order groceries and staples online and get them delivered to your door. E-grocery stores became one of the biggest disasters in the dotcom debacle a few years back. But a handful of them are beginning to resurface, with more sure to follow.
Some sites are still regional, but
amazon.com announced the nationwide opening of its grocery store this summer, with 14,000 nonperishable items, some hard to find and many discounted. Amazon offers free shipping on orders over $25. To see which e-grocer operates in your neck of the woods, check out
safeway.com,
peapod.com,
freshdirect.com and
netgrocer.com."
