Here is the breakdown of ticket prices and fees:

Per Person Price
The per person price is the set price for the event/attraction. This is the amount that is received by the website owner, and is usually the same price you would pay if you purchase the tickets in-person.

Service Fee/Charge and Order Processing Fee
There is usually a service fee per-ticket that is retained by the online payment processing company. This fee is not usually charged on in-person retail outlet or box office purchases.

City, state, and local taxes (provincial and Federal Goods and Services taxes in Canada) are not included in the per person price of the ticket.
