Good grief! How do you do that for free? Can you do it without them knowing it?
Background checks cost $$. But if you just ASK them if you can do one on them....they'll run for the hills and you can save yourself the money. *chuckle* Publicdata.com and KnowX.com are the two I use. You can do it without them knowing...if you know their first/last name and city/state. It's not good to invade someone's privacy unless you think you may want to meet them..... which is why I'm pretty up-front about it.
