Line Shopping: Find the Best Odds Every Time

What is line shopping?

Line shopping means checking odds at multiple sportsbooks before placing a bet and choosing the one that offers the best price. It's the betting equivalent of comparing prices before making a purchase — except in betting, even small price differences compound into significant money over time.

If you've decided to bet on the Eagles moneyline, you don't just take whatever your default sportsbook offers. You check DraftKings, FanDuel, BetMGM, Caesars, and others. If one book offers +160 and another offers +150, that 10-cent difference means $10 more profit on every $100 bet that wins. Over a full season of betting, those differences are the margin between breaking even and being profitable.

Why odds differ across sportsbooks

Sportsbooks don't all set their odds the same way. Several factors drive price discrepancies:

• Different models and data: Each sportsbook uses proprietary algorithms and data sources to set opening lines. Their underlying probability estimates differ, which produces different odds.
• Betting action imbalances: When heavy money comes in on one side at a specific book, that book adjusts its line to manage risk. Other books that haven't seen the same action may lag behind, creating temporary price gaps.
• Different vig margins: Some books operate on thinner margins than others. A low-vig book might offer -105/-105 on a spread where a high-vig book has -110/-110. That difference goes straight to your bottom line.
• Promotional pricing: Sportsbooks sometimes offer boosted odds or reduced vig on specific markets to attract action. These promotions can create genuine value even on markets that are otherwise efficiently priced.

The math: how a few cents add up

Let's quantify the impact. Suppose you bet $100 on one game per day, 300 days a year. Your base win rate is 52% on spread bets (a skilled bettor).

Same bettor, same picks, same win rate. The only difference is taking -105 instead of -110 — and it turns a losing year into a profitable one. That five-cent improvement in average odds is worth over $675 annually on just $100 bets. Scale that up with larger wagers and the impact is dramatic.

How to line shop effectively

Effective line shopping requires accounts at multiple sportsbooks and a fast way to compare prices. Here's the practical approach:

1. Open accounts at 4-6+ sportsbooks. The more books you have access to, the more likely you'll find the best price. Focus on the major operators available in your state.
2. Use an odds comparison tool. Manually checking each app before every bet is tedious. The DawBets odds comparison tool shows real-time prices from 20+ books in a single view, sorted by best available odds.
3. Check for +EV before betting. Line shopping finds the best price, but expected value analysis tells you whether the bet is worth making at all. The best price on a bad bet is still a bad bet.
4. Act quickly on outlier prices. When one book is significantly out of line, the price often corrects within minutes. Speed matters for capturing the best value.

Common line shopping mistakes

Even bettors who understand line shopping sometimes make errors that reduce its effectiveness:

• Only using one or two books: The value of line shopping increases with each additional sportsbook. With two books, you'll find a better price about 30% of the time. With six books, that jumps to over 70%.
• Ignoring player props: Mainstream markets (spreads, totals) are priced more efficiently. Player props and alternate lines often have the widest price discrepancies between books — that's where line shopping delivers the most value.
• Chasing stale lines: An outlier price might be stale (not yet updated). Check that the game time and market are current before placing a bet on what looks like an unusually good number.
