I have $375 and I want to buy 10 shares of MPV.  

 

Do I spent $350.00 on my MPV Rights and have $25.00 walking around money ?  or do I spend $358.00 in the market, pay my $9.00 commision, and have only $8.00 walking around money ?

 

What's liquidity worth ?  What am I missing ?  Thanks to all.
