How to Get the Best Odds (Line Shopping)
Taking the best available price on every bet is the simplest, most reliable edge in betting. Here's how line shopping works and why it matters so much.
Line shopping — comparing prices across bookmakers and exchanges and always taking the best — is the easiest edge in betting and the one most casual punters ignore. Over time it can be the difference between winning and losing. This guide explains how to do it and why it works, building on what is a bookmaker's margin (overround)?.
Why prices differ
Bookmakers price the same event differently based on their models, their liabilities and where money has gone. On any given bet, one firm is usually offering a noticeably better price than the rest.
Taking that best price shrinks the effective margin you pay on every bet.
Small edges compound
Consistently getting even 2-3% better odds turns a break-even bettor into a winning one over thousands of bets. It directly raises your effective ROI at no extra risk.
You can compare prices instantly with an odds comparison site, then place the bet where it's biggest.
Exchanges often win
Betting exchanges frequently offer the best available prices because of their low margins — see what is a lay bet? (betting exchanges explained). Factor the exchange commission into the comparison.
For popular markets especially, the exchange price is a strong benchmark for fair value.
Line shopping and tipsters
Line shopping is how you close the gap between a tipster's advised price and what you can actually get — the advised vs available odds problem. Act fast and shop, and you'll get closer to the record.
