Line shopping is simply checking the odds for the same bet at multiple sportsbooks and taking the best price, and it is the easiest edge available to any bettor.

Odds differ because books have different customers, liabilities and opinions, so one book may offer -110 while another offers -105 or even +100 on the same team.

Over hundreds of bets, taking -105 instead of -110 lowers your break-even win rate from 52.4% to 51.2%, which turns marginal bettors into profitable ones.

Open accounts at three to five reputable, licensed books, compare prices with an odds comparison site or manually, and place the bet only at the best available price.
