What Is Line Shopping?
Line shopping is the practice of comparing odds on the same bet across multiple sportsbooks and placing your wager at the book offering the best price. It's the sports betting equivalent of checking Amazon, Walmart, and Target before buying the same product — you want the lowest cost or the highest return for the exact same item.
Every sportsbook sets its own odds. DraftKings might list the Buffalo Bills at −3.5 (−110), while FanDuel has them at −3.5 (−105), and BetMGM offers −3 (−110). These differences look small, but over hundreds of bets they create a massive gap in your bottom line.
Line shopping is universally regarded as the single easiest, lowest-effort edge available to sports bettors. You don't need a model, a system, or advanced math. You just need accounts at multiple sportsbooks and the discipline to check before you bet.
Why Do Different Sportsbooks Have Different Odds?
Sportsbooks don't all copy the same number. Their odds diverge for several reasons:
- Different risk positions. If DraftKings has taken heavy action on the Chiefs, they might shade their line to attract bets on the other side. FanDuel's customer base may be betting differently, producing a different line.
- Different market-making models. Some books (like Pinnacle or Circa) use sharp, low-margin pricing. Others (like DraftKings or BetMGM) target recreational bettors with wider margins and promotional pricing.
- Speed of adjustment. When injury news breaks or sharp money moves a line, some books adjust instantly while others lag. That lag creates temporary price differences.
- Promotional pricing. Sportsbooks sometimes boost odds on popular games to attract customers (e.g., "Bet $5 on the Lakers, get +200"). These promotions create real pricing discrepancies.
A Concrete Example: The Profit Difference Between −110 and +100
Suppose you want to bet on the over 45.5 points in an NFL game. Two sportsbooks are offering different prices:
| Sportsbook | Odds | $100 Bet Profit (if win) |
|---|---|---|
| DraftKings | Over 45.5 (−110) | $90.91 |
| FanDuel | Over 45.5 (+100) | $100.00 |
By placing the same bet at FanDuel instead of DraftKings, you earn an extra $9.09 per $100 wagered every time this bet wins. On a single bet, $9 might not seem life-changing. But bettors don't make one bet — they make hundreds.
How Line Shopping Impacts 1,000 Bets
Let's quantify the cumulative effect. Assume you're a moderately active bettor placing 1,000 bets per year at an average stake of $100. You win roughly 52.4% of the time (the break-even rate at −110 juice).
| Scenario | Average Odds | Net Profit Over 1,000 Bets |
|---|---|---|
| Always bet at −110 (no line shopping) | −110 | −$200 (slight loss due to vig) |
| Line shop and average −105 | −105 | +$1,250 |
| Line shop and average −102 | −102 | +$2,340 |
The difference between lazily betting at one book and diligently line shopping can be thousands of dollars per year — with the same picks, the same sports knowledge, and the same bet volume. You're not getting smarter at handicapping; you're just paying less vig.
Even if you're a losing bettor, line shopping reduces your losses. And if you're a break-even bettor, it can push you into profitability.
Which Sportsbooks Tend to Have the Best Lines?
Not all sportsbooks are created equal. Here's a general hierarchy based on market sharpness and pricing:
Sharpest Lines (Best for Reference)
- Pinnacle — The gold standard for sharp odds, available internationally but not in most US states. Used as a devigging reference.
- Circa Sports — A sharp US-based book available in Nevada, Colorado, Iowa, and Kentucky. Welcomes sharp action.
Competitive Recreational Books
- FanDuel — Frequently offers the best odds among major US books, particularly on NFL and NBA spreads and totals.
- DraftKings — Competitive pricing with frequent promos and odds boosts that create additional value.
- BetRivers — Often overlooked, but regularly posts competitive lines, especially on alternate markets.
Higher-Margin Books (Check but Don't Default To)
- BetMGM — Lines tend to be slightly wider but occasionally outlier-priced on specific markets.
- Caesars Sportsbook — Similar to BetMGM; check for specific opportunities rather than betting here by default.
- PointsBet — Unique markets and occasionally sharp pricing on smaller sports.
The best strategy is to check all of them. The book with the best line changes from event to event and market to market.
How to Line Shop Efficiently
The Manual Approach
- Decide on the bet you want to make (e.g., Lakers −4.5).
- Open each sportsbook app or website.
- Navigate to the same game and market.
- Compare the odds.
- Place the bet at the book with the best price.
This works for one or two bets, but it becomes tedious when you're evaluating an entire slate of NFL games or scanning player prop markets.
The Efficient Approach: Odds Comparison Tools
Odds comparison tools aggregate real-time odds from multiple sportsbooks into a single view. Instead of tabbing between eight apps, you see every book's price for every market on one screen.
WagerWiz's odds screener does exactly this — and goes further by highlighting which book offers the best price, how the current odds compare to the devigged fair line, and whether a given bet crosses the +EV threshold.
Why WagerWiz's Odds Screener Makes Line Shopping Instant
WagerWiz pulls live odds from DraftKings, FanDuel, BetMGM, Caesars, PointsBet, BetRivers, and other major sportsbooks. For every market across NFL, NBA, MLB, NHL, NCAAF, NCAAB, soccer, tennis, and more, the screener shows:
- Side-by-side odds from every book in a single table
- The best available line highlighted so you see it immediately
- The devigged fair odds so you know whether the best line is also +EV
- Filters by sport, league, market type, and sportsbook so you can zero in on exactly what you're looking for
What used to take 15 minutes of switching between apps now takes seconds. And because you're seeing real-time data, you can act before the best line disappears.
Line Shopping and +EV Betting: A Natural Pair
Line shopping doesn't just save you money on vig — it directly feeds into a +EV betting strategy. Here's why:
- Devig a sharp line (e.g., Pinnacle) to establish fair odds.
- Line shop across recreational books to find the best available price.
- Calculate EV using the best price you found.
The best price is more likely to be +EV than the average price. Line shopping is how you find the books that are furthest from the efficient market price — and those are exactly the spots where +EV edges live.
Key Takeaways
| Principle | Detail |
|---|---|
| Always compare | Check 4–6 sportsbooks minimum before placing any bet |
| Focus on the spread | Even half a point or 5 cents of juice matters over time |
| Use tools | An odds screener like WagerWiz eliminates the tedium |
| Pair with +EV betting | The best line is the foundation of every +EV calculation |
| Track your savings | Log which book you bet at and what the next-best price was |
Line shopping requires no advanced skill — just discipline and the right tools. It's the easiest edge in sports betting, and leaving it on the table is like voluntarily paying full price when there's a coupon sitting right next to you.
FAQ
How many sportsbook accounts do I need for effective line shopping?
At minimum, four to six accounts at major sportsbooks will give you meaningful coverage. The most common combination for US bettors includes DraftKings, FanDuel, BetMGM, Caesars, and BetRivers. Adding books like PointsBet, Fanatics, and Hard Rock Bet increases your chances of finding outlier prices.
Does line shopping really matter for casual bettors?
Absolutely. Even if you only bet $20 per game, the difference between −110 and +100 on a winning bet is an extra $5.45. Over the course of a season, those savings add up to hundreds of dollars. Line shopping is proportionally valuable at any stakes.
Is line shopping the same as arbitrage betting?
No. Line shopping means finding the best price for a bet you already want to make. Arbitrage betting means betting on both sides of an event across different books to lock in a guaranteed profit. Line shopping is a best practice for every bettor; arbing is a specific strategy that requires betting on all outcomes.
How fast do the best lines disappear?
It depends on the market. Main lines (spreads, totals) for major sports can hold for minutes to hours. Player props and alternative markets can move within seconds, especially once sharp bettors start hitting them. Real-time tools like WagerWiz help you spot and act on the best prices before they're gone.
Can I line shop for live bets?
Yes, but it's much harder because in-game odds change rapidly and not all books update at the same speed. WagerWiz supports live odds comparison for supported markets, which makes live line shopping far more practical than doing it manually.
