Ticket prices if bought in the US

Hey guys, I'm from California coming up to pemby this summer for the second time. The first time I went I lived in Canada, and I already have my ticket but my friend also from California is coming too. When she buys her ticket, will it be in USD (ga pass is 260$) SO for her she only pays 260 or will they charge her 354 (or whatever the exact price is)? Just a little confused.
