Line Shopping: The Cheapest Edge in Betting

TL;DR
The same bet is priced differently at different books. Always taking the best available number is the closest thing to free money in this hobby — worth several percent a year with zero prediction skill required.
Same bet, different price
Tonight a hitter's Over 0.5 hits might be -162 at DraftKings and -148 at another book. Identical bet. If you take the worse price out of loyalty or laziness, you paid a tax nobody charged you.
Over hundreds of bets, taking the best number is worth real percentage points — often more than most handicapping "systems" deliver.
Why prices differ at all
Books balance their own risk. One book took heavy action on an Over and shaded the price; another didn't. Sharp-respected books (like Pinnacle) move on sharp money; recreational books move on volume. Those philosophies drift apart during the day — and every gap is your opportunity.
Book disagreement is also information: when the sharpest book is meaningfully different from the rest, that's a hint about where informed money sits.
Make it a reflex
Before any bet: check the price at every book you have. Our Market Pulse board does the comparison for you — DraftKings vs. FanDuel vs. Pinnacle on the same prop, best price highlighted in green with the gap in points. Ten seconds of checking, permanent discount.
