Marketing has proposed a contest to drive our customers to "like" us on Facebook. The prize value is $500.
Basically, the contest will first require the entrant to become a fan of our facebook page by indicating that they ‘like’ us. Once the person has done this, they will officially register for the contest by accessing our Guest Book on our main webpage (not facebook).
Would this be considered a lottery and do we need to open it to the general public or can it just be directed toward customers?
