I bought a total of 5 and cancelled 3.
So what do you vote in your own poll?
2-4 - because you effectively bought 2.
4-6 - Because you bought 5.
Booked and cancelled - because you cancelled 3 tickets.
Ontop of that, if I purchased 4, 6, 8, or 10 tickets, there are two options/ranges on the poll that are applicable to me.
