What does SEARS need with this info? Honestly, this just smells bad. I won't call them evil just yet but this is pretty serious from a privacy POV.
Also, isn't it about time we push for a law that makes these privacy agreements shorter and in english (not legalese). One thing I like about CC is that they have a layman's terms version of all their licenses as well as the legalese ones. Not only would people be more likely to read them but it makes it hard for companies to bury important info several pages deep.
I realize that the layman's version would be long as heck but it's better then nothing (and people would STILL be more likely to read it since they can understand it without thinking to hard).
