I'm co-hosting a savings contest with FNBO Direct, the online arm of 150-year-old First National Bank of Omaha.

To enter, you submit a one-minute video explaining what you're saving for and why. FNBO Direct will choose five folks from the entries to be contestants in its Pay Yourself First Challenge. Each will get a dollar-for-dollar match of what they save during the six-month contest, up to $5,000, and the grand prize winner will get a spa vacation.

You can find out more, including the official rules and how to enter, at PYFChallenge.com.

ShopSmart recently singled out the best store-branded credit cards--along with a few you should skip.

(If you haven't run across it yet, ShopSmart is a relatively new magazine from Consumers Union and it's worth checking out. Think Real Simple meets Consumer Reports: nice design, fun to read and plenty of worthwhile advice and tips inside.)

Some highlights:

The best cash-back store cards include Costco American Express (1% on every dollar spent at Costco or other retailers, 2% on airline, hotel charges, rental cars and cruises, and 3% on restaurants and gas stations) and Wal-Mart Discover Card (0.25% to 1% of every dollar you spend, with the rebates increasing the more you spend).

The best for loyal customers include Ann Taylor Visa (4% on every dollar spent at Ann Taylor locations and anntaylor.com, and 1% spent elsewhere); Barnes & Noble MasterCard (5% back on most store items, plus one point for each dollar charged elsewhere. 2,500 points earn a $25 gift certificate); Bloomingdale’s Visa (3% reward for every dollar spent in the store and 1% for purchases made elsewhere. Requires $1,000 in Bloomie’s purchases annually); Macy’s Visa (up to a 3% reward for every dollar spent at Macy’s, and 1% on purchases elsewhere, good toward gift certificates after you spend $500) and Target Visa (one point per dollar spent at Target and one point per $2 spent elsewhere; 1,000 points earn you 10% off one day of purchases.

Some to skip: Abercrombie & Fitch, Crate & Barrel and Lowe’s, which have no rewards programs.

But if you're serious about rewards (and don't carry credit card balances), you'll also want to check beyond the universe of store cards. Starwood American Express, for example, is a great card for those who want travel rewards, and American Express Blue Cash is at the top of my list for cash back rebates. For more, check out my MSN column, "The 15 most rewarding credit cards."

If you've got a sunny patch of lawn or even a patio, you can grow vegetables to cut your food bill and please your palate.

Two of the easiest to grow: tomatoes and sweet peppers. (Sweet peppers are one of the five foods that shot up the most in price in the past year, as I wrote in "High food prices? Here's how to save.")

If you've never grown anything, start small and don't over-invest in supplies. If you're patio gardening, you'll need a cheap pot or two, potting soil, seedings, stakes and maybe a little Miracle Grow. Otherwise, you'll need just the seedlings, stakes and Miracle Grow.

You can buy stakes or wire cages, or make your own with four three-foot sticks looped with twine.

Put a note on your calendar to check and water the plants every few days. If you're plagued with slugs or snails, a simple beer trap will get 'em--just bury a plastic bowl near the plants so the top is level with the ground, and fill it with cheap beer. The critters will be attracted by the smell and will go willingly to their doom.

If you're still unclear why you need to get copies of your FICO scores before applying for a big loan, read "Lender's goof slams credit scores."

Sallie Mae included the wrong code in a recent download of account information to credit bureau Equifax. The code it applied to customers with graduated payment plans--where you make smaller payments at the start, which later grow--is actually meant to be used on borrowers who haven't kept up with their payments. In other words, Sallie Mae reported up to 1 million of its customers as delinquent, and trashed their Equifax credit scores. Some scores fell more than 100 points, from the "excellent" range to near-subprime.

Someone who pulled a credit report, rather than getting her scores, would have been hard-pressed to detect the little change that made such a difference. The annotation, "arrangements made to make partial payments," was tucked away under "descriptions" in the borrower's Sallie Mae account entry. Elsewhere, everything would look fine; in the summary, the loan would still say "paid as agreed."

Sallie Mae says it has fixed the error and all seems to have returned to normal. But this should serve as a warning. Even though credit reports have become easier to read, don't assume you know what they're saying. Before a major loan, get your FICO scores, so you know what lenders are seeing.

We’re back from a two-week trip in which I abstained from blogging, though not from working. Sorry for the long radio silence.

But we tried out a few travel tips and confirmed our love for a few others. If you’re planning a summer vacation away, these might help you save money and have a more pleasant trip:

1. Pack a hot pot. A hot pot is one of those little electric kettles you plug into a socket to boil water. (I fondly remember the burnt-orange one that allowed me to subsist on ramen noodles during college.) We used ours to make oatmeal, tea, hot chocolate and the occasional pot of French-pressed coffee (yes, we packed that too—clearly space was not at a premium). Not only did we save a ton of money on overpriced breakfasts, but there’s nothing like an evening hot cocoa to please a kid—or a cup of organic green tea to please her mom.

2. Bring scented tea candles. They’re easy to pack, and they’ll clear a hotel room of most weird smells. Our floor in a Washington, DC hotel was non-smoking, but you’d never know it—the ventillation system disgorged the smog from the smoker one floor below. As long as he or she wasn’t actively puffing, though, the candles dispatched the stench in a few minutes’ time.

3. Take a cooler on the plane. We have a collapsible fabric one that we started using when our daughter is an infant, but I’d bring it along now even if I didn’t need to keep her in snacks. Airplane food has long been awful, and now it’s expensive and a diet-killer besides. We had a nice selection of fruit, carrots, soy chips, Curves bars and peanut butter sandwiches to keep us satisfied on that long stretch between security and baggage claim. Just remember: don’t pack liquids (you can buy drinks if you want after you clear security) or anything even vaguely fluid-like. We lost a nearly full jar of peanut butter to TSA on a previous trip.

4. Visit the corner grocery shortly after you arrive. Most urban hotels have one nearby; if you’re headed for a resort, you can pay the cab driver a few extra bucks to wait while you make a quick shopping trip for staples.

5. Budget for help. Three bucks for a Smart Carte, two bucks per bag (plus tip) for sky caps, one or two bucks a bag for bellmen…it all adds up, but wrestling with bags and lines is a serious downer. Some of the money we saved by making some of our own meals was well spent paying for various kinds of help.

As gas prices soar, many of us are looking for ways to contain the damage. Edmunds.com points out a simple way to save big:

Stop driving like a maniac.

"If you are currently an aggressive driver (cruising speeds from 75-85 mph, constantly accelerating and changing lanes and braking sharply) and you decided to calm down (driving with the cruise control set to 65 mph), your fuel economy would improve an average of 35 percent," Edmunds recently announced in its latest research, "We test the tips."

This behavioral change had a far bigger impact than the other commonly-heard advice about improving fuel economy, such as properly inflating your tires (3.75%) or driving your pickup with the tailgate down to reduce drag (1%).

If gas is $4 a gallon (as it already is in some locations in Los Angeles), someone who drives 15,000 a year and gets 15.5 m.p.g. driving aggressively could save $986 a year by driving more calmly to get 20.5 m.p.g. Aggressive driving also increases the odds you'll get into an accident and wind up with higher insurance premiums to boot.

So, zen out. Set your cruise control. Breathe deeply. And save money.

There's one downside to managing your money well...you tend to become the "go to" person when your less responsible family members (and friends) run into financial trouble.

Some people just say "no" to any requests for cash, no matter the emergency, but others want to help when they can. Here are three things to keep in mind:

1. Don't commit right away. The person asking you for money has probably been perfecting his or her pitch for days. By contrast, you've had no time to consider your response, so don't rush into a commitment. "I need to think about this--I'll call you back" or "I can't loan money without checking with my spouse" are legitimate answers that will buy you some time to consider your options.

2. Make it clear whether this is a gift or a loan. You should never lend money you can't afford to lose, which means that you should be prepared for any loan to become an inadvertent gift. But you'll increase your chances of getting at least some of the money back if you formalize a loan arrangement with a written agreement that spells out the amount loaned, the interest rate charged (if any), the expected payment and any penalties for failing to make payments. For big loans, consider using a service like Virgin Money (formerly CircleLending), which charges $199 to set up a loan agreement and $9 a month to do the loan servicing (accepting and crediting payments, sending email reminders, etc.)

3. Don't agree to co-sign unless you can, and will, make all the payments. Co-signing a loan means putting your good credit in someone else's hands. Don't do it unless you'll be the one in charge of making the payments and you're prepared to make every single one.
