1. John goes to a coupon site.

2. John signs up to get coupons, but instead of entering his real email address he uses "buystuff.john1234@surfspamfree.com".

3. John gets coupons in his regular email in-box each week.

4. John, unfortunately, starts to get tons of new junk mail along with those coupons.

5. John goes to his Surf Spam Free account and disables his buystuff.john1234@surfspamfree.com address stopping any further spam before it gets to his real in-box.

6. John is happy.
