This morning I went to my local Sams and came away with a Nexus and 4 year warranty for about the same as I paid at the google play store.
A four year warranty you say! How much did it cost? Do you expect it to actually be easy and useful if it breaks in a few years? (As you may tell, I have a low opinion sometimes of these third-party warranty services... do you have to keep your original receipt for 4 years?)
