Fuel vouchers are useless to me as I have a company fuel card for my car, I haven't bought petrol in 10 years so it would be good if I got the 30 points instead.

I guess Woolworths have worked out how the system needs to work to be profitable for them. If it is not viable for them to offer points below $30 then they won't offer them no matter how many people write to them about it.

The points are a good extra but you should still shop where you get the best value for you.
