1. Manage your finances Use Mint for getting a complete view of your finances. CreditSesame, Credit, CreditKarma, and Quizzle for free credit score tracking.

Vanguard has a great selection of index funds. Matrix ITA for airfare prices. yapta for tracking airfare prices over time.
2. Get three free credit reports every year Set a Google calendar event to get a free report every four months rotating between Equifax, Transunion, and Experian (major credit report providers) via annualcreditreport.com. Each company is bound to provide you with one free report once a year.
3. Return policies are really lax in CA (and the US in general) Buy almost anything including electronic gadgets like phones and laptops to try. If you don’t like it just return it within a set time period, usually 15 days or 30 days, for free.
4. Healthcare The US has one of the most expensive health cares in the world. Employers provide health insurance - medical, dental, and vision. For healthy individuals, usually, the less expensive plan (HMO) is a better option. Dental insurance usually covers two teeth cleaning per year for free. Vision insurance covers one vision test, which is usually not free but with a nominal co-payment. Medical insurance usually covers a physical checkup.
