Tradestion comisions

What are real commision?

On their web site they inform as follow:
- stocks 0,001$ per share under 500 shares (1$ min)
- stocks 0,0006$ per share over 500 shares (1$ min)
- equities min deposit is 5.000,00$

It`s clear for me, but what about platform costs?
- Tradestation platform $99.95/month if account doesn't meet the minimum criteria (activity - 5.000 shares preceding month)
- TradeStation WebTrading - free

If Tradestation Webtrading is free what is the difference between
Tradestion platform and Tradestation Webtrading?
Are there any other cost i should know about?
Thank you for your answers.
