Important note to avoid getting a ton of SPAM in your email box!
None of us want a bunch of SPAM/junk emails in our email boxes. I suggest that if you are going to sign up for free samples and/or do trials that you get an email address specifically for that purpose (personally, I have had over 50 different email addresses for this purpose!). It's very simple to get a free email. Just go to www.gmail.com and sign up for one. Once you have your free email address you can use that email for any freebies you sign up for!
