Promo codes and sign-up offers

Sign-up and refer-a-friend offers at the books on the Margus board whose terms we could confirm on their own pages, with the date we last checked. More books are added as their terms are confirmed.

These are the books' own offers. Margus has no deals or codes with them and does not take bets. Offers change and vary by location, and age rules vary by book and state. Gambling problem? Call 1-800-GAMBLER.
