I thought I should go ahead and share this with you in case you are the kind of person (like me) that enjoys a chance at winning a $50 Visa Gift Card. Yup, that’s right, Filtrete is giving away a Visa Gift Card worth $50 to registered users at Filtrete.com who review one of their products. If I am reading the contest details correctly, it looks like they will be giving away one prize every month to a lucky reviewer. You can review up to 5 items on the site and receive an entry for each one.
