Sportsbook promotions are some of the best value in betting, yet most bettors capture only a fraction of it. These ten mistakes are the usual reasons.
1. Using bonus bets on heavy favorites
A $100 bonus bet at −300 returns only $33 if it wins, because the stake is not returned. At +300 it returns $300. Use bonus bets on longer odds, roughly +250 to +500. (Converting bonus bets.)
2. Using no-sweat bets on favorites
The refund only matters if the bet loses. A no-sweat bet on a −250 favorite has little chance of triggering it. Use longer odds. (No-sweat bets.)
3. Boosting same-game parlays by default
A 50% boost on a parlay with a 30% hidden margin can still leave you −EV. Boost straight bets you can price. (Profit boosts.)
4. Ignoring playthrough
A big deposit match with 15× playthrough can cost more to clear than it is worth. Do the math first. (Deposit match and playthrough.)
5. Letting bonus bets expire
Many expire in 7 days. Set a reminder or convert them immediately.
6. Not maxing +EV promos
If a boost is +EV and capped at $25, bet the $25. Betting $5 on a good promo leaves value behind.
7. Hedging at a bad price
The hedge price decides how much of a promo you keep. Check every book for the best opposite price, not just the one you use most. (Hedging sportsbook promos.)
8. Mixing promo results with regular results
Promo profits are real, but they make your regular betting look better than it is. Track them separately. (How to track sports bets.)
9. Chasing promos with money you cannot afford
A bigger deposit to unlock a bigger bonus is only sensible if the money is genuinely spare. Never deposit bill money for a promo.
10. Breaking the terms
Multiple accounts, someone else's account, location spoofing or betting from a state where the book is not licensed can forfeit your winnings and your account. Use one account per book, in your name, where it is legal.
A simple promo routine
- Check each book's promo tab once a day (or let a tool collect them).
- Run each promo through the right calculator: boost, bonus bet, hedge.
- Take only the +EV ones; max them.
- Hedge when you want certainty, using the best price available.
- Log everything with a "promo" tag.

Frequently asked questions
What is the biggest mistake with bonus bets?
Using them on short odds. Because the stake is not returned, bonus bets are worth much more on longer odds.
Are sportsbook promos worth it?
Most welcome offers and many ongoing promos are worth taking if you use them on the right odds and hedge or convert carefully.
Should I hedge every sportsbook promo?
Not necessarily. Hedging locks in profit but gives up some expected value. Hedge when certainty matters more to you than maximum EV.
