i got the extended warranty on my 47" LCD from bestbuy. yup i plan on fucking it up right before the ext. warranty ends so i can get a new one
and they're not a bad buy it depends on what the cover. if it covers, bestbuy will replace it if you break it. so get the extended warranty from them. a lot of other places won't and it also depends on the product. you wouldn't get it on something like a pair of headphones or and item you can throw away and don't really care about replacing.
