Sears for instance offers an extended waranty, at an expensive price for even just a three year policy, which also cancels out the original maufacturers waranty....
I got my newest FL set from a mom and pop dealer, great rebates, and they gave me 100.00 off for buying the set, and their regular prices were cheaper than lowes, homo depot, and sears sale prices...plus I got the extended waranty that takes over after the first year runs out and then it kicks in...it cost 30.00 per year for the set...I bought it for 9 years...which I have a full 10 year waranty....try beating that!....this extended price and coverage is a one time deal to cover one unit or a whole houseful, as long as their all on the same receipt, and you can extend it when it runs out!...try that at many stores, not happening!
