Agree that operators should have speedy withdrawal options. In many jurisdictions they take your money instantly, but take from three days to over a week to let the customer withdraw. Banks don't do this, Sportsbooks should not be allowed either. 

Also concur with point brought up previously that promotional bonuses and free plays should terms should be stated clearly. Too many online Sportsbooks and Casinos have additional info boy the promotion in fine print, and these are many times unattainable. Many of the best operators rarely offer bonuses or free plays. And when they do offer these, the rules are clear.
