I love buying raffle tickets, entering contests, etc.
I don't win very often but it does entice me to at least think about buying something.
I'll surely buy those raffle tickets for the LI Lighthouse Challenge- even if I don't make it to the event itself.
I enter sweepstakes all the time online- I even have an e-mail address I use just for that so I get most of my junk emails at that address.
