Great question, Gail! Thanks for asking.
The Angie's List Magazine has done quite a few articles about Home Warranties in the past. This one is from May:

. and you can find other links to articles in that area as well.
Home warranty companies have been on our most-complained-about category list year after year, so if you're thinking about purchasing one, be sure to check Angie's List for a reliable company others in your area have had great experiences with.
I hope this helps! Let me know if this article wasn't correct or if you couldn't find the one you were referring to. :)
