Matchbooks odds on horses are the best I have ever seen.

For example Summer Bird at the track is 5 1/2 to 1 but on matchbook its 10-1 and you can lock it in at 10-1 unlike at the track where you bet 5 1/2 to 1 and it could drop to 4-1 by race time and thats what you get.

Another example is Mine that Bird the Derby winner. At the track he is 13-1 but at matchbook he's 38-1 .Thats a huge huge difference
