I remember
@Zacobite suggesting an insurance to cancel flights with full refund. That's the best way to book in smartbuy i guess. That way you can cancel and book new ticket.

One more issue I found was, if the OTA has 3 ticket pricing options (like saver, regular etc), Smartbuy provides only the first option, so one might not even get checkin luggage. When contacted, customer support just said that's the way the software works currently, sorry for the inconvenience.
