Those who have bought devices from the Play store. What is this 15% restocking fee nonsense?

So my new Nexus 4 has some kind of stain on the camera lens that leaves a black smudge on every photo. I want to send it back and apparently Google charges a 15% restocking fee on any return if you even opened the box? Is this for real or just jargon that does not necessarily apply for devices that are obviously defective?

The notion that google makes me wait 8 weeks to ship a phone, sends me a flawed device, and then wants to charge me 15% to send it back plus shipping both ways makes me never want to buy anything on there again.
