Line Shopping 101: How to Find the Best Odds
Line shopping is the practice of comparing odds across multiple sportsbooks to find the best available price for a bet. It is one of the most impactful yet underutilized strategies in sports betting. While it requires a bit of setup and effort, the long-term savings are substantial, often the difference between a losing year and a profitable one.
Why Line Shopping Matters
Different sportsbooks set different odds on the same events. One book might have the Dallas Cowboys at -3.5 (-110) while another has them at -3 (-110). That half-point difference may seem trivial, but it converts a losing bet into a push (and a refund) in a meaningful percentage of games.
Similarly, one book might offer the over at 47.5 (-110) while another has it at 48 (-105). Finding the extra half-point or the reduced vig adds up over hundreds of bets. Studies have shown that consistent line shopping can improve a bettor's bottom line by 1-3% over time. That might sound small, but it can mean the difference between a 2% loss rate and a 1% profit rate, turning a losing hobby into a winning one.
The math is simple. If you place 500 bets a year at $50 each, a 1% improvement from line shopping saves you $250. A 3% improvement saves $750. Over five years, that is $1,250 to $3,750, essentially free money from spending an extra two minutes comparing prices before each bet.
How to Set Up for Line Shopping
The foundation of line shopping is having accounts at multiple sportsbooks. Most experienced bettors maintain 3 to 6 active accounts. You should fund each account with enough money to place your standard bets without needing to transfer funds between books constantly.

Tools for Comparing Odds
Manually checking 5 sportsbook apps for every bet is tedious. Odds comparison tools solve this problem:
These tools display the odds from multiple books side by side, highlighting the best available price for each side of a bet. Some even calculate the expected value difference and alert you when a significant discrepancy appears.
Common Line Shopping Scenarios
**Scenario 1: Half-point saves.** You want the Chiefs -7.5. Four books have -7.5 (-110), but one has -7 (-115). In the NFL, games land on 7 about 4% of the time, so that half point is worth paying a little extra vig for.
**Scenario 2: Vig comparison.** You want the Celtics moneyline. One book has -160, another has -155, and a third has -150. Betting at -150 instead of -160 saves you real money on every wager.
**Scenario 3: Alternate lines.** Some books offer alternate spreads and totals. You might find a more favorable number at the same vig by checking alternate line options across books.
Key Numbers in NFL Line Shopping
In football, certain numbers carry outsized importance because games frequently land on them. The key numbers are 3 (games decided by a field goal) and 7 (a touchdown). Getting a spread of -2.5 instead of -3 or +3.5 instead of +3 is enormously valuable. Approximately 15% of NFL games are decided by exactly 3 points. Line shopping specifically for these key numbers is one of the highest-value activities a football bettor can do.

Frequently Asked Questions
How many sportsbook accounts do I need for effective line shopping?
A minimum of three is recommended, but five to six is ideal for comprehensive coverage. The marginal value of each additional book decreases, so three gives you most of the benefit without excessive complexity. See [state guide](/states) for legality and which sportsbooks operate in your area.
Is line shopping really worth the effort for small bettors?
Yes. Even if you bet just $20 per game, getting -3 instead of -3.5 or -105 instead of -110 protects your bankroll. The percentage savings are the same regardless of your bet size. Over a full season, even small bettors save enough to fund several extra wagers.
Will sportsbooks ban me for line shopping?
Line shopping itself will not get you banned. Sportsbooks do limit accounts that consistently beat the closing line, and line shoppers are more likely to get the best number. However, recreational bettors who line shop occasionally have nothing to worry about. It is the sharp, high-volume bettors who face potential account restrictions.
