FFS leave GST alone Chippy

[Wainuiguy]

So if this week kumera were $4.99 a kilo, then next week GST comes off.  You go back to the same supermarket but rather than $4.24 (the price it should be after GST is removed)  the kumera are $5.49 a kg.  Did you save the GST?

all other things being equal, most definitely YES - but as you mention earlier, other factors like supply issues and natural disasters affect market prices, all the time to be honest, so expecting the price for some items to be the same week on week is illogical...  The reality is a kilo of Kumera on that day in your scenario would have been 6.30 ish if it was not for the GST free. 

You cannot assert that the GST free but doesn't work and use unrelated market movements due to other factors as the the reason...

Which means over time there will be no way to show if GST has just been absorbed into the price - which just exactly what experts, including the Minister of Finance, have been saying.  The very reason Grant Robertson poured cold water on the idea in May.
