Need pampering but don't want to pay a lot for this muffler massage? Enter Lifebooker, a smart way to book spa and salon appointments while saving up to 50% on them.

The free service allows you to search for appointments by time and discount, with services ranging from waxing to acupuncture to hair extensions. You can then book online. Couldn't be easier, and there are deals to be had. (I scoped an hour-long facial for just $42.25.) The only drawback? It's available only in New York and Los Angeles now, but here's hoping to a nationwide rollout over time. After all, the ability to book on the fly — while shaving down your total bill — is a beautiful thing.
