Do you mean contributing by providing incorrect and irrelevant information that the OP had to correct while being falsely accused of contradicting himself? No thanks.
You usually give good advice but I think you missed the mark on this one.
I won't be dragged into another pointless argument. Just felt the need to restore some balance and say my piece. Let's move on.
@sumyunggai what kind of alcohol are you thinking of bringing in that comes in 300ml?
If you end up trying your method, please post back the results, it could be very useful.
Again my point, they are sneaky, since hardly any bottles come in 300ml, only half bottles 350 / 375 etc so then they can say oi you are .75 over, then charge you the tax on the FULL amount, since you are over the limit
You know how they think and work here, being smart to make the limit less than any bottle sizes that are made
And for sure they won't allow unsealed / open bottles without "testing" contents first
