My charger has stopped working, it is only a year old and has no frayed or exposed wires.

Question

My charger is about a year old and has been working perfectly until today. It has no frayed parts or any wires exposed on it. i plugged it in and it wasn't charging and my battery icon on my monitor had an x on the inside of it and wouldn't charge. I tried again to charge it after it finally died and it didn't work, I used my mom's charger and it worked perfectly fine, so it isn't the batter that is having a problem. Has my charger just spontaneously stopped working or it is a common flaw that occours often with other users, and if so is there a soloution to fix it or get a discount on a new charger for what I am going to assume is a design flaw in the box on the charger because that is the only other thing I can think of that would be causing my charger any problems?

I had a lightbulb once. Brand new. Screwed it in its socket, lit it up. 20 minutes later it was dead. It's "brother" from the same twinpak is still shining bright almost 2 years later. Same thing here. The manufacturing process only guarantees that the mean time between failures is adequately long. But the individual units follow a probabilistic bell curve: sometimes you get one from one end and dies right off, most times you get one from the middle and lasts awhile, occasionally you get one from the other end and seems to last forever.
If you have AppleCare, it will be replaced for free. Else you will have to pay the $79 we all have. Of the 8 Mac portables I've owned, in only one did the power brick die on me. Replaced it at my cost, watched the Mac die a month later.
