Costco Travel Savings
While also being able to cheaply satisfy unhealthy sugar addictions, Costco offers some pretty rad, cheap travel deals. I've used it before to snag cheap car rentals, but it can also be used to book vacation packages and cruises to select destinations. But keep your eyes on cheap travel; don't be tempted by their sign-up bonus credit card offer!

To hear from those with more experience in these matters, check out Million Mile Secrets to see their new series on Costco travel.
