My macbook pro's power cord malfunctioned and broke so the first place I took it to was this apple store. After waiting patiently for a genius employee, I filled out a replacement form and walked away with a brand new one, only to have this new one break also. So I took it back to the same store, and simply got a replacement new one from the shelf with no questions asked. Their replacement policy here is great. The manager promotes great customer service.
