I hate it when I see it. There is nothing I can do short of being the person trying to stop people from doing the wrong thing. I learned a long time ago, you cannot stop a person determined to do the wrong thing.
This is my short VloMo 2012 contribution to take a humorous way to explaining.
Basically, a company rents a shiny car from a local car dealer. Then they rent car space in your local mall. People fill out a detail contest sheet with a lot of personal information, much more than what is needed for a contest.
On the back, in teeny tiny type they will tell you that you must fill out the info completely or it will be rejected. Or if you are under 18 it will be rejected. Or if your income is too low you will be rejected.
In some states you cannot will $100,000. You might have a chance at $5,000. Or $199. Depends on where you live.
If you "qualify" then you get to the next level, a timeshare meeting. You have to attended. You will then be given the hard sell on purchasing a timeshare. If you survive then you might walk out with steak knives. Or a radio. Not sure what the mooks who survive get these days.
Oh, should you happen to win the $100,000 you do know that you have to pay taxes on it right?
