thanks Tassi,
i agree, i've been trying to "insert the card" then press "savings", but what i'm finding is with the modern terminals (hand held), they have already calculated the fee. so say i bought dinner on saturday at $70. The terminal said i owed $70.80 so there was no way to vary the fee pending on Visa/amex/eftpos.
I'll take it up with our MP, fees should be abolished (cost of living, the big banks make $10 billion each already)
