Best Buy, Inc. (NYSE: BBY) continues to be the innovator in the consumer electronics space. The next time you saunter into an airport and plop out your laptop and cellphone, you may see a bright yellow Best Buy Express kiosk nearby.

That's right -- Best Buy is testing a concept to have the most-needed gadgets and accessories available for retail sale at an automated kiosk in your nearest airport terminal. Get ready to whip out that credit card.

If you forgot to charge that cellphone (oh no!) or need a last-minute Christmas gift after you arrive at the airport, you may soon be in luck. Initially, Best Buy is going to have these kiosks available at 12 major international airports in the U.S. to test the concept. The pricing? Very similar to what you'd find in a typical Best Buy retail location (read: cheap). This will be a comfort to those who are tired of paying those over-inflated fees at airport shops.

These kiosks will match the wish list of every gadget-hungry traveler: MP3 players, digital cameras, unlocked cell phones, portable gaming systems and all kinds of chargers for all your electronic toys. Want some headphones for the plane? You'll find those as well. Even Best Buy gift cards will be available -- the one-size-fits-all holiday gift. This is a very innovative approach by Best Buy to grow sales in a captive audience, and should provide a decent lift to upcoming holiday season sales.
