I'm interning at Amazon at the moment, and I can say that as far as office perks go, they don't have many. But when it comes to the connivence of living, they do far more than I would have ever expected.
For example, I got corporate housed pretty far away from work (hour by bus), Amazon not only payed for a shuttle every morning to work and every night from work, they also reduced my housing costs and offered a rental car for the summer. And this wasn't just to me, every intern that didn't get housed right next to campus got some sort of benefit to make getting to work easier.
They take almost the opposite approach to some places. They assume you'll take care of yourself at work, and then they take care of you outside of work.
I think that's because they want to maintain the culture of frugality on-campus. Wastefulness on the job is pernicious because it adds up and cannot be tracked the way employee benefits can.
Another point is that internship programs are for recruiting. I expect that Amazon's internship program and all its perks cost less per hire than their regular recruiting process.
