How does Best Buy's warranty work?

So I got a 2 year warranty on my Zune at Best Buy. My Zune is now not holding its charge anymore. So if I bring my Zune to Best Buy and have them replace it, will I still have my warranty or will I have to buy another for another 30 dollars?

buy another

I think you have to mail it in, they wouldnt let me return my psp with the warranty i bought with it. those bastards

Well when you mailed in your PSP did they just fix it and set it back and you didnt have to buy a new warranty?

For me if I have to buy a new one, Ill just keep my Zune until the 2nd gen comes out and then exchange it.

i had to replace an mp3 player i got online and i had a 2 year warranty too and after you replace your item you still have your warranty. its their psp dealy its worth investing in if you buy a high priced item. hell they didnt have the same mp3 player so i got a better one to replace it and it didnt cost me a thing. wicked nice.
