Time for Shopping & Travel!

Get tickets to the big game or concert
At first glance, StubHub looks a lot like eBay, which isn’t very Web 2.0. However, StubHub lets you skip over traditional ticket-buying from sites like Ticketmaster, letting you network and buy and sell tickets directly with other fans who share the same interests, all through a Web-based auction interface. eBay bought the company in January for $310 million, so StubHub must be onto something good.

Get travel deals the easy way
Kayak helps you search for airfare, hotel and car-rental deals, and then sends you directly to the sites themselves – including low-cost carriers like JetBlue. This way you get the lowest prices, and Kayak doesn’t take a chunk out for itself; the company is supported by travel companies.

Find out what’s on sale near you
You can continue to hoard those huge, messy circulars in Sunday newspapers. Or, you can skip the hassle and use Judy’s Book, a collection of everything that’s on sale in your neighborhood, with or without coupon codes. Mark down everything you want, print out a copy, and hit the local stores. Leave the newspaper at home and the scissors in your desk drawer where they belong.

Shop (and eat) ’til you drop
Kind of like Citysearch, Epinions, and Friendster rolled into one site, Yelp lets you conduct local searches for just about any kind of store or restaurant. Read reviews from the locals down in the trenches; you can get a good idea of how to weigh a particular review by reading what else that person likes and dislikes. It also means you’ll find fewer “shills” – people who give positive reviews only to their friends (or their own) restaurants and shops.

Find out how much that house is really worth
When shopping for a house, you can’t always trust the ads or advice from a broker. Zillow uses satellite maps and existing sale-price data to calculate reasonably accurate valuations for homes (within a claimed 7.2 percent). Zillow isn’t a panacea, however; a small percentage of estimates can be wildly inaccurate, and it has trouble with New York co-ops according to one report in the Wall Street Journal
