Line Shopping: The Single Biggest Edge Available to You

The math is brutal but simple

If you bet -110 on every game, you need to win 52.4% to break even. If the same bet is available at -105 across the street and you take that, you only need 51.2%. Over a thousand bets, that 1.2% is the difference between losing $5,000 and breaking even.

Line shopping is the single biggest edge available to a recreational bettor. It costs you nothing but the time it takes to open a few apps before placing a bet.

How many books should you have?

Three is the minimum. Five is the practical maximum unless you're an active sharp. The five we recommend:

1. DraftKings — best for SGPs, broadest prop menu
2. FanDuel — sharpest sides on NFL/NBA, fast PayPal withdrawals
3. BetMGM — live betting, MGM Rewards
4. Caesars — profit boost tokens, parlay insurance
5. Fanatics — newest book, softest prop pricing

How to actually shop

Build a habit:

1. Decide on your bet first. Don't open the apps and let the lines pick your bet — that's how you tilt into bad numbers.
2. Open all your apps, find the same market on each, and write down the prices.
3. Take the best price. If two are tied, pick the book with the larger limits.
4. Track which book had the best price. Over a few months you'll know who's sharp on what.

The number to remember

Half a point on an NFL spread is worth roughly 2-3 cents on the moneyline. So a -3 (-110) versus -2.5 (-115) is roughly a wash. But -3 (-110) versus -2.5 (-105) is a real win — same probability, better price.

Bonus: cross-book parlays

You can't run a parlay across two different books, but you can hedge across them. Bet your favorite at the sharp number on FanDuel, then if the line moves your way, hedge the other side at DraftKings to lock middle equity.

Bottom line

If you only do one thing differently this season, get four sportsbook accounts and shop every line.
