you still can..... if you are not paying anything to SI right now then you are just getting the basic membership. Basic is better then almost every other service like this on the net. But, basic does not show you the over/under percentages. Not sure if it ever has. Premium is 70$ a month, it is the same as it was last year and no price increase there. They added some new services and call their new package premium pro, basically like dealing with a portfolio at this point. They offered it for 300$ for the year for all sports. Now they are saying if you up with a sportsbook they suggest you can get a month free. Betus is an example of this. It is really nothing more then a referal bonus. They track how many people take advantage of this and BETUS gives SI a commision. It is the same thing forums do for contests. From my position, I have never had a problem with BETUS and I find them to constantly have the some of the best dog lines you can find. If you are looking for sites like SI that offer the same stuff for less you will not find anything close to the quality they put out but some others to look at.....
sportsbook.com- just one books numbers, some times unreliable, free
wagerline- same type of info, but these are really just votes on which side you are on with no money significance. there have been reports that votes do not show the same results as tracking actual bets.
let me know if you have any more questions.
