Travel Zoo

Travel Zoo will e-mail you the best travel deals in your area each week. I've gotten a heads up when a particular airline was having a massive sale and, thanks to Travel Zoo, bought my ticket (I believe it was BOS-JFK $29 each way) before the deal sold out. They also inform you of hotel, entertainment and other travel-related deals.

Row Nine

Row Nine (<-- private referral link) is a site exactly like Rue La La.  May as well join to have maximum selection of amazing brand name deals.

Rue La La

Rue La La (<-- it's a private, referral only site, so join through my link) is a great site. They host many "boutiques" each week of top name brands (think Theory, Tumbuk2, Sorel, Illy, Guess, Reebok, Calvin Klein, etc.).  I've bought a few items from them at majorly reduced prices (usually at least 50% off). You have to be quick, though, because their items sell out fast (that's because the deals are so awesome). 

LivingSocial

LivingSocial (<-- click for a $5 referral bonus!) is yet another site like Groupon. Daily deals in your area for at least 50% off (are you tired of me writing this yet?).  Hey, at least it gives you a heck of a deal selection every day.  I've purchased deals from this site for luxury escapes, restaurants and massages.  Click my link above for a special $5 bonus to get you started. That can take care of half the cost of some deals!

Groupon

If you haven't heard about Groupon (<---link) yet, you probably live under a rock (or in a city they don't cover yet, like Helena, Montana (sorry, no deals for you!).  This site is free to join and if you request it, they will email you a deal in your city each day.  The deals are usually at least 50% off original prices.  There have been deals on restaurants, bars, salons, vacations, retail stores, spas (I love the massage deals), gyms, yoga studios, events (like a dessertfest, truffle making workshop or ladies' night out) and more.  I've saved lots of $$ buying Groupons (is that in the dictionary yet? If not, it should be) for things I do and places I eat anyway (and for ones I'd like to try).  You've got nothing to lose if you sign up for Groupon!

MyPoints

MyPoints (<--- click on this link for 100 bonus points) is one of the first sites I joined back in '95.  Yes, I've been an active member for 17 years. Wow, that makes me sound old. You earn points on this site for doing lots of stuff, including:  reading emails, clicking on links, searching the web, rating websites, playing games, shopping (say, if you normally shop at Bestbuy.com or want to rent a car through Avis.com or even book a flight through United.com or use any of their other 100s of merchants, you can earn lots of points for those purchases).  They also have printable grocery coupons!
    In my 15 years, I've earned 48,635 points. The very first prize I earned was a $50 gift certificate to Tower Records (man, do I really, really feel old now).  I think I then went on to purchase my very first CD with that gift certificate (I think it was Ugly Kid Joe. I liked their "Cats in the Cradle" cover).  Given how expensive CDs were back then, I probably only had about $20 left on that thing afterwards, but it was totally worth it!!
    Since then, I've earned countless gift certificates (which means over $500 worth) to Amazon.com, iTunes and other merchants I am too drunk to remember right now. Either way, click on my link to MyPoints. It's worth your time.
