When I rent movies, do I devour the DVD extras? Sure, lots of times the audio commentary is just a track of actors and directors waxing important and mostly ignoring the images on the screen, but they can still be dishy and insidery, and for my favorite movies, they can almost make purchasing the DVD worth the money.

Disney DVD knows there are lots of fans like me. For years, it has released its biggest titles in a variety of volumes. There's often a simple one-disc version for people who just want to see the movie without any extras, and maybe a two-disc version loaded up with more outtakes and mini-documentaries.

Travel may be down in this economy, but there's one area where business is booming: discount booking sites. With travel providers desperate to unload unused rooms and tickets, it seems like the only sectors of the travel industry that are exploding are the ones previously seen as a last resort by the industry.

Priceline.com reported that bookings through its site, which offers steep discounts on hotel rooms and other travel products, are at their best levels in nine years. Hotwire.com, which is owned by Expedia, reports a similar boost in revenue. The Hotwire Group's sales over 12 months have exceeded $250 million for the first time, and reps told WalletPop that compared to last year, hotel bookings in the biggest markets (meaning the most popular travelers' cities) are up between 20% and 30%.

A good buy doesn't always end up on your receipt at the register. Sometimes it winds up on your résumé.

According to the College Board, the average college tuition in the United States is $26,273, up more than 4% from last year. But not all universities cost that much, and not all cheap colleges give you junk degrees. Sprinkled across America you'll find some discount degrees that are actually worth just as much as the highest-priced ones.

Tuition at all of these colleges can be had for under $5,000 a year -- and a few are completely free. If your kid's in high school, now is the time to start thinking about how to afford their next big step. Start planning your applications now, because the competition is tight:

Michael Moloney, the prolific Extreme Makeover: Home Edition designer, recently contacted WalletPop by Skype to divulge a few choice tips for renovating your home on a budget. One of his essential suggestions: When you've got no money to transform your surroundings, you can achieve a dramatic effect by simply painting them.

Moloney's ideas were so good that this week, in advance of Sunday's episode on ABC featuring country music ditz Kellie Pickler, WalletPop's Jason Cochran wanted to talk with Moloney again to get more. Today, Moloney has a few words for all the people who pester him on the street to ask him to work his magic on their own houses.

After the peso crisis of 2001, Argentina became the destination célèbre for Americans, who flocked to South America to revel in the astonishing buys that a devalued currency can yield. Time has passed, and now we're slogging through our own economic turmoil. So is a trip to Buenos Aires still a great buy, or have the locals caught on to the influx and jacked up rates to milk tourist dollars?

Michael Luongo, author of Frommer's Buenos Aires, visits WalletPop's studios to tell us that the answer is a little bit of both. He lets us know what the situation is in the storied colonial capital of Argentina, and he fills us in on how a first-time visitor there can still find deals without losing the authenticity of the local culture. Sure, you've seem washed-up reality stars do the tango on Dancing with the Stars, but is it feasible to dance it in the real Argentine milongueros?

As part of our ongoing series, WalletPop tells you how to go for less:

Quick! Describe Mickey Mouse's personality in six words or less. Having a hard time? All right, what was the last wacky thing you saw him do? Still stumped?

Mickey is a lot of things, but specific he isn't. One of the world's most identifiable characters has become little more than a corporate mascot who is rolled out whenever the Disney company needs to sell something. Mickey is a placebo, a blank slate of a cherub upon whom children and adults alike can project their fondest make-believe fantasies. Even when he makes personal appearances, he's usually silent.

Mickey could be said to be stuck in 1955, but Disney is aware it's nearly 2010. So its image-makers, aware that Mickey's "aw-shucks" act has grown stale and won't last forever in a world filled with ironic and savvy kids, are taking a risk with their flagship character. Breaking the code Mickey has followed for the past half-century, it has authorized a new image for His Mouseness, which could turn off millions of parents who treasure the genial personality they're used to. Harking back to his early years, he'll become a colorized version of his 1930s self: wiry legs, sharp angles, a stockier belly, a whip-like rodent tail, and a peaked brow that can twist into a variety of perturbed expressions to match his flashing temper.

Royal Caribbean's newest behemoth, the Oasis of the Seas, doesn't arrive in our waters for another couple of weeks, but pictures of the awesome cruise ship are already appearing in the news.

How could they not? She's the largest cruise ship on the planet, towering 20 stories over the waves and cutting a 1,180-foot-long profile against the horizon. On board, there's space for 6,300 paying guests, 2,000 crew members, a 1,300-seat theater (larger than some on Broadway), some duplex cabins, an ice rink, an indoor/outdoor park, and a cocktail bar that travels from deck to deck via an elevator system.

WalletPop will be on board for her maiden voyage out of Fort Lauderdale on Nov. 20, and our own Jason Cochran will bring you video proof of this astonishing new feat of engineering.

Survey after survey confirms what you and I already know: Staycations are stupid. You and I don't just hate the stupid word, which was dreamed up by opportunistic marketing departments to sell old things in a new way. We also hate the idea of them, and as soon as the money starts flowing again, we're outta here.

But there's also no doubt that more of us are staying closer to home right now. Due both to a downturn in personal spending and a cutback in business travel expenses, America's hotels and airlines are dramatically less full nowadays than they were three years ago.

The urge to explore, being an inherent and eternal quality of mankind, hasn't left us; only the means to explore have. Still, it's also true that the longer this mess persists, the more travel will be changed forever. Some shifts have already been cemented into place.

In the next generation of Disney Cruise Line ships, the windowless inside cabin may be the ones kids beg their parents to book. In a boon to budget travelers, the cheapest, least desirable cruise stateroom category will be getting a major sexing up in January of 2011, when the Disney Dream, now under construction, is christened.

All inside cabins on the new Dream will be equipped with an oh-so-Disney innovation: the "virtual porthole." Above the bed, a round TV window will be embedded in the wall, made to look like an old-fashioned ship's porthole. Through it, the tenants in the modern equivalent of steerage will be able to watch live, streaming high-def images of the ocean outside, just as the guests in more expensive cabins see it for real.

Lots of us find that at the end of the month, we don't have any money left. The recession has forced millions of Americans to put off dreams of renovating or redesigning their homes. Designer Michael Moloney has a gift for quick and effective decor. After all, he whips up stunning new rooms within days every week on ABC's Extreme Makeover: Home Edition.

Taking off from the show's episode this Sunday, in which a family's plans to build their dream home are derailed by a freak accident, Moloney calls in to WalletPop's studios to talk with Jason Cochran about the things you can do if you find you can't afford that dream makeover anymore.

You can whittle down the things you already own. You can freshen things up by moving your stuff all around the house to new locations. Or, if you have $14 left in your pocket by the 31st, you can give any room a dramatic new look with one simple solution.

Watch our conversation with the design whiz below. You can also watch our conversation with music star Xzibit, who is making his second appearance on the show this weekend as he pitches in to help another needy family.
