I found out a few weeks ago that the minimum FVF on the $1 promo is $1(.10). I sold something for $10 and got hit $1.10, not $1.09. No point complaining as a reading of the headline shows that is now 'pay only $1'. Or something like that.

 

I realise that 1c is neither here nor there, but it's the principle.

 

I now make sure I don't use the promo for anything $10 or less posted.

Why $1.09 ......   $1  FVF  +  10%  GST  =  $1.10

$10 sale = 99c (9.9%) + 10% = 10c = $1.09.
