You have a secret shopper score

It's not them, it's you. Wireless carriers, retailers, airlines — they've all given you a score, a secret rating that determines all sorts of customer service perks, said Khadeeja Safdar at The Wall Street Journal. Called the customer lifetime value, or CLV, the rating can affect the upgrades or discounts you're offered, invitations to VIP events — or even your wait time when you call to complain. The data used to calculate your score can range from how often you browse items online to whether you often return items or wait for sales. "Unlike credit scores, CLVs aren't available to consumers and aren't monitored by any government agency." In some ways, though, the scores are just "high-tech versions of what shopkeepers have done for generations": They make judgments based on how customers look or behave.

Prenups aren't just about money

If you think prenups are just for celebrities, you're wrong, said Jillian Berman at Market​Watch. There are some unexpected reasons more couples are considering prenups — an agreement about how you split assets in the event of divorce — such as protecting the right to use frozen embryos for in vitro fertilization. And you'd do well to think early on about what will happen with a business launched during the marriage. "All of my retirement assets went into building this business," says one entrepreneur, who felt that giving her ex-husband a share, as they would have shared retirement savings, was the fair way to go.
