According to a notice I received, sometime August 10 Gain will be giving out free samples on their Facebook page. Once you like them you will be able to fill out the form, but not until August 10!
Make sure you check back often though they could go fast!
Go to http://www.facebook.com/gain?ref=ts&v=app_4949752878 to see if you can get a sample!
