If you haven't noticed I have added a Free Sample and Coupons bar on the right hand side towards the bottom. Take a look at the items and sign up for free samples. Everyone loves free stuff.
Some people sign up for an additional e-mail account to use when they sign up for free things or promotional offers. That's a pretty smart idea. I don't mind getting the promotional e-mails, I just deleted the ones I am not interested in. I seem to manage it pretty well. Don't be afraid to sign up for free things.
