Ebates.com– An easy and free website I use to get cash back on all of my online purchases. See my review of the site here.
RecyleBank.com– A free website I use where I take quizzes and learn about the environment in exchange for points I then use to get free magazines, coupons, and other rewards. Read my review here.
Orbitz.com– I really love their three days before and three days after search option that can be used to learn which days would be better to travel on in order to save me money.
Priceline.com– I love this site for travel because it allows me to compare airfare sites and always gives the lowest prices, plus all prices include taxes and fees upfront. You aren’t seeing a low price on one page only to get sticker shock on the next. I especially love this site for hotel deals.
