A few years ago I was ordering a computer online for my dad. I got all the way to checkout and saw the little box that asked if I had a promotional code. Curious, I did a quick web search and came up with one. I plugged it in and instantly saved over $200 on the purchase.

Promotional codes, good for shopping discounts, free shipping, and other freebies, have become pretty common in the online shopping world. If you regularly check the Hot Hotel Deals page, you know I often list a promotional code that gets you access to a package vacation deal. I recently spoke to Barry Boone, founder of CurrentCodes.com, which collects coupon codes for, among other things, travel. Hotels, airfare, even a new suitcase can be had at a discount with codes found on Barry's site.

I checked the travel section of CurrentCodes.com today and found codes for several Las Vegas hotels, including MGM Grand, Luxor, and Mandalay Bay. The site also listed codes for Orbitz, Southwest Airlines Vacations, and Travelocity, and even discounts on merchandise at Brookstone.

Also on CurrentCodes.com was a $5 off coupon for a site I hadn't known about before (and wish I did for this past weekend's trip to New York City with a baby in tow; more on that later): BabiesTravelLite. The service ships baby formula, diapers, wipes, baby food, even bathtubs to hotels and resorts around the world. Much better than trying to negotiate with airport security on how much liquid formula you really need to take on the plane.
