Line Shopping 101: Why You Need Multiple Sportsbooks
Introduction
If you're serious about sports betting, there's one fundamental practice that separates winning bettors from the rest: line shopping. This simple yet powerful strategy can significantly boost your long-term profitability without requiring any advanced handicapping skills.
In this comprehensive guide, we'll break down everything you need to know about line shopping, from the mathematical foundations to practical implementation strategies.
What is Line Shopping?
Line shopping is the practice of comparing odds across multiple sportsbooks to find the best available price for any given bet. Just like you wouldn't buy a car without comparing prices at different dealerships, smart bettors never place a wager without first checking multiple betting sites.
The Mathematical Impact
Let's start with a simple example that demonstrates why line shopping matters:
Example: NFL Sunday Game
- Team A vs Team B
- Sportsbook X: Team A -3 (-110)
- Sportsbook Y: Team A -2.5 (-105)
- Sportsbook Z: Team A -3 (-105)
If you believe Team A will win by more than 3 points, Sportsbook Y offers the best value at -2.5. If you think it'll be close to exactly 3, Sportsbook Z gives you better juice at -105 instead of -110.
The ROI Difference
Here's where the math gets compelling. A bettor who consistently gets -105 lines instead of -110 improves their breakeven point from 52.38% to 51.22% - that's a 1.16% improvement in required accuracy.
Over the course of 1,000 bets at $100 each:
- Standard -110 bettor needs 524 wins to break even
- Line shopping bettor needs only 512 wins to break even
- That's 12 fewer correct picks needed for the same result
Real-World Line Shopping Examples
Example 1: NBA Totals
Lakers vs Warriors Total Points
- DraftKings: Over 230.5 (-110)
- FanDuel: Over 229.5 (-108)
- BetMGM: Over 231 (-115)
- Caesars: Over 230 (-105)
Best Play: If you like the Over, Caesars at 230 (-105) offers the lowest total with better juice.
Example 2: NFL Point Spreads
Chiefs vs Bills
- Circa Sports: Chiefs -1.5 (-105)
- Westgate: Chiefs -2 (-110)
- BetRivers: Chiefs -1.5 (-115)
- PointsBet: Chiefs -1 (-110)
Best Play: PointsBet at Chiefs -1 gives you the most favorable spread.

Advanced Line Shopping Strategies
Steam Chasing
When you see a line move dramatically across multiple books (called steam), it often indicates sharp money. Line shopping helps you:
- Catch the old number at books that haven't moved yet
- Find the best price on the new number if you want to follow the steam
Arbitrage Opportunities
Occasionally, line shopping reveals arbitrage opportunities where you can bet both sides and guarantee a profit:
Example:
- Book A: Team X +3.5 (-105)
- Book B: Team Y -3 (-105)
You can bet both sides and win regardless of the outcome.
Middle Opportunities
Similar to arbitrage, but you're looking for scenarios where both bets can win:
Example:
- Monday: Bet Team A +7 (-110)
- Wednesday: Line moves to Team A +4
- Bet Team B -4 (-110)
If Team A loses by 5, 6, or 7 points, both bets win.
Common Line Shopping Mistakes
1. Chasing Bad Numbers
Don't bet a game just because you found a good line. The line shopping should support your existing handicapping, not drive it.
2. Over-Complicating Simple Bets
Sometimes the difference between -110 and -108 isn't worth the extra effort for small bet sizes.
3. Ignoring Withdrawal Terms
Some books have complicated withdrawal requirements. Factor this into your decision-making.
4. Poor Bankroll Distribution
Don't chase a slightly better line if it means putting money in an unreliable book.
