I know this isn't much of an answer but I think it depends on the item. For example, I bought a $32 toy and toys-r-us tried to sell me a warranty that was $12. Doesn't really make sense. But the warranty on my flat screen TV is probably a good value. -- On a side note, it is wonderful that items are so cheap now that we have to consider the value of the warranty but I am worried about out throw-away society. I had a neighbor that just bought a new lawn mower because it leaked oil. That would cost $12 to fix. Oy!
