1. Never Bet Because of an Emotional Attachment to a Team or Player

It can be tempting to bet on your favorite team, especially if they’re having a great season. However, you should never bet simply because of an emotional attachment to a team or player.

Whenever possible, you should always use promo codes when signing up for SI Sportsbook bonuses. This will ensure that you get the best possible deal on your bet.

As much as we like the SI Sportsbook promo selection, its bonus withdrawal is a bit on the slow side. Especially after using something like BetMGM, you can really tell a difference in this one.

Not only that, but you’re also limited on your withdrawal options: Play+ or bank transfer. While both options are free, you have to withdrawal at least $10. What’s more, even though process times are as quick as 24 hours, bet settling can take up to 72 hours in most cases.

But if you can look past these minor caveats, you will find appealing SI Sportsbook bonus code offerings and an enjoyable user experience.

SI Sportsbook’s bonuses are definitely worth taking advantage of, especially if you’re a new user looking for fast bet boosting. And with the $300 SI Sportsbook welcome bonus, you have 300 reasons to maximize your bets.

Even existing users have a lot to appreciate here, as there are numerous bonuses and promos to keep you coming back for more.
