I got an email from Caesars saying that if I opened up an online betting account at Caesars (administered by William Hill, apparently) and bet specifically $10 on the over/under on Sunday night's Dallas/Minnesota game, I'd get a $100 free bet. The promo for the account signup is CR101.
I can't use this, because I live in Oregon and online betting isn't allowed. However, if you live somewhere where it is allowed, you might be able to take advantage of this. A $10 bet will cost you about fifty cents in expectation (they didn't say you had to bet one side or the other, so, your choice), and a $100 free bet is worth $50, so it may be worth a shot.
If anybody tries this (and you would have to be in a state where online betting is allowed), let us know if it works!
