There is a new way to get some free samples through the US Post Office. The only kicker is that they are searching for people who meet certain demographics, so you may or may not qualify (meaning you might not get the samples). Head on over here to see if you qualify or not. If that link does not work, try to copy and paste this into your browser:

Some of the items in this set of samples is Reeses, Ben Gay, Grill Mates and Secret Clinical. You can find the details of the progam by heading here (scroll down through the articles to find this one).
