When you register, depending on the game, you can get so many games depending on the game, but usually I have noticed on Sandboxplus that you get 1 team, and 1 salary cap league. As a grandfather member, my credit card is charge $3.95 per month. Sadly, new members will have to pay $4.95 per month, and there are options, where you can pay for a game a one-team fee for the entire MLB season, as an example, or you can have some pay-cal program for your payment.
I know that if you signed-up for AFL football at Sandboxplus, there are DEALS, where you get 2 months of baseball for FREE. Take into consideration that you can win big-money, if you do well. I am not talking about like $10.00 or $20.00, but Full Count gives out a $5,000.00 winner, and also FREE membership, if you do well. If you are not a grandfather member, then it is more complicated thru the payment channels.
If you can create cohesiveness at the Forums at Sandboxplus, you can really parlee in some competitive leagues. Of course, the nay-sayers will say that I could play in a free league and be competitive, but the propensity is more likely to be active in a pay-league.
