I should just buy this ticket

Holy crap i found a multicity ticket to vegas, denver, costa rica, and back to austin for about $550. i need to just buy this ticket and that will make me bust my ass and save the money that i need to head to costa rica for a month and a week in the other cities. Holy shit!!! I am excited. If the price is the same at the end of the week i am just going to buy it. Hooray me!!!
