Hi guys,
Got the NZ Farmsource card recently and it seems to have a good 12c discount at BP/Z.
Is it possible to ‘save’ 6c/L fuel discount you get at the pump each time, but use the farmsource card to get the 12c. And then at the end of the month use up the saved 6c/L or more to get a bigger discount (and use farmsource to pay for it again)?
Hope this makes sense.

I have a farmsource/RD1 card. You'll see normal non discouned price at the pump, no other discounts can apply but you'll see the farmsource discount when you get the bill at the end of the month.
