Too many books out there...
but there is only one book that has the most options...5dimes and then TheGreek is next.
Everytime I sign up w/ a book to see what they offer I usually get an email or a call on making my 1st deposit and I never do because they offer no options. Cant parlay quarters, 1st 5 innings, Basketball quarters or NHL periods..damn shame because they could get my bizz if they did...JMO
