When you purchase an appliance at one of the major stores such as Sears, HH Gregg, or Walmart, you will undoubtedly be asked to buy an extended warranty.
I have no problem with purchasing an extended warranty because most of them are not that expensive and could be a good deal in the long run. What you must do is research a little and see the record of how the company stands by its warranties.
For example, I purchased a 50 inch television in HH Gregg, and in about a year I had a problem with it. The company along with the warranty company work together and in a short period of time replace my TV with a new one.
In Walmart, my experience was just the opposite. I purchased a lawnmower and in less than three months, I had major problems with it. I contacted the store manager and he could have cared less. He said to take it to the warranty company. So; you must be very careful if the company backs up the warranty, it's a good thing. If they don't care such as WALMART, you will be in the mercy of the warranty company. It took me more than a week to contact them but, they told me to go find a company to fix it. With all the hassle? I won't be buying a lawnmower at Walmart! It's not worth all the hassle.
Do yourself a favor and research the companies before you make a major purchase. This could save you a lot of stress and money.
As for me? My lawnmower is still in the shop for almost three weeks now. It means, I did hire a lawn guy to trim the grass for $90. That Sucks!
