Ticket Galaxy extra charges, tax on tax South Windsor Connecticut

I purchased tickets to my home city baseball game, 5 tickets.. they charged me $215 on my invoice plus 'delivery of my e-ticket' aka emailing it to me.  Then $53 for a misc expence?  So fine, let's call that tax.. its $276 on my bill.  Great.  What do I see on my credit card statment?  $375!!  What the ficking hell.  nearly $400 for 5 $43 tickets.  Tell me how that makes any sense whatsoever, and also, why I wasn't informed of the total before I agreed to pay it??  Now I'm pissed off about this game which are my sons first baseball games.  Thanks, jerks, for overcharging me!!!
