FREE LASIK for texting???

I listen to Kidd Kraddick in the Morning and Big Al and Kelli have been promoting a pretty interesting text campaign involving LASIK surgery.  Basically you text "winwin" to "51737" and you can win a free procedure if you are chosen.  Key-Whitman Eye Center is running the campaign and its a great way to increase their prospect list.  If people are interested in free LASIK surgery they are probably interested in paying for it if they don't win.
