It seems to me that there could be a bit of an "underground economy" when it comes to casino free play offers.
I frequently get in the mail free play offers at various casinos in other cities that I don't travel to. I think it would be rather easy to send my player's card to someone in that city (along with pass code) so a friend could play the free play.
This could work if there were a coupon (card must be inserted to validate the free play coupon), or if the free play requires a code to download the credits.
Without revealing names of casinos or companies has anyone done this -- shipped off the coupon or code with your players card to a friend in another city?
I recall Caears/Total Rewards had a promotion a year or so ago that required play in a certain number of casinos around the country for some sort of prize. On another forum, players were talking about exchanging player cards in the mail with the required minimum bet money to score a credit in the promotion. Did anyone participate in that?
