Snail Mail Spam

I don't know if anyone else deals with this, but it seems that as soon as I pee'd on that pregnancy test and it came out positive that I've started getting all sorts of spam and junk in the mail regarding baby and what not. Why am I suddenly getting all these offers in the mail for things I don't need. I'm sorry that I don't want to become a member at your church just to have my child baptized... etc! Where do these people get our information from, it's so irritating!
