$12 is cost for an outward ticket at bestonwardticket.com that is in your name -- and good for a period of time that you choose. My friend did arrive in BKK and immigration had a trainee at the desk who did ask him about onward travel bcs he arrived on one way ticket. He is professional and was last in Thailand 3 years ago. He simply showed his booking -- from website given. It is authentic ticket that is later canceled by that agency.
