Checking odds across different platforms is the only way to survive in this game long term. If you just stick to one bookie, you are willingly giving away money. I usually keep a few tabs open on matchdays to lock in the highest possible value. For football, I frequently cross-reference with 1-x-bet-cameroon.com because their underdog prices tend to stay higher close to kickoff. My tip is simple: stop being lazy and compare lines every single time.
