Cool but overpriced, Here's an alternative

They certainly have a great selection of products and a cool looking website with a lot of social features. However, aside from the branded products, which they do flash sales on. I'm not sure if they deliver the best price value.

So why is fab.com expensive? Because you can find many of their products on Amazon for the same price.
#1: I think you are paying for the millions of dollars they spend advertising on facebook
#2: They spend a lot on designing the webpage to look cool (which cost money)
#3: The thousands of products they list causes them to have high inventory cost, a cost they need to pass on to consumers

There are many other websites out there that sell similar products. One website I've come across is www.pandasundae.com. (They sell everything from quick inflate travel pillows, mini humidifiers to cheap underwater cameras)
PROS:
#1: Founder is based in Asia so they can go direct and sourcing cost is cheap
#2: Good customer service (they responded to my questions over email pretty quickly). They also have good reviews on www.Yotpo.com
#3: Fun product selection, even though it might seem confusing sometimes
CONS:
#1: They website looks clean and nice, but doesn't have a lot of social media hook ins/ bells and whistles
#2: Longer shipping window (standard shipping is 2 weeks)
