So that when you FINISH THE CHALLENGE I can send you a check back for your Contest Fees plus your prize winnings..You are not selling anything? Why do you need my CC# then? BS.
Last week all the winners of the Fall Challenge got a check for $137.50 each.
$50 in, $137.50 returned.
Not a bad investment considering all of them lost at least the 10% they wanted to....
Unless of course you have no intention of actually finishing the challenge, in which case it would be far better not to start.
