It's important to note how the best NFL betting promos work, with some sports betting sites providing bonus bets when you place a qualifying wager. Others might issue money back as bonus bets if your opening NFL wager ends up losing.

Be sure to read the terms and conditions for NFL betting bonuses. Sometimes you will be required to enter NFL betting promo codes when you sign up for a new account to claim bonus bets.

When you place your first bet, you will either be paid out as a winner or getting your losing stake refunded as a bonus bet. This can be up to the value of $1,000.
