Philo, a small skinny-bundle TV streaming service, is offering $5 off if you refer a friend to sign up. That may not seem like much of a discount, but it makes the cheapest live-TV streaming service even cheaper -- and there's no limit to how many $5 discounts you can stack up. 

Launched in November, Philo, the latest virtual TV services to emerge in the last three years, is also the cheapest and most niche. Most of its competitors -- like AT&T's DirecTV Now, Google's YouTube TV, Dish's Sling TV or Sony's PlayStation Vue -- offer wider collections of channels at costs starting at $20 to $40 a month. To keep its price low, Philo scorns live sports channels, like ESPN, that are the most expensive programming in a consumer's cable bill. Philo offers a seriously skinny bundle of cable TV networks like AMC and Discovery at the cheapest price available, $16 a month.
