Indeed. The Tax Dept is one where I did pay the surchage as the extra 0.5 point to me is worth more than the additional surchage.
In using cards you often have to doa quick mental calculation to decide what is best.
ie I use my Citibank (free for life) VISA at JB Hifi despite it transferring at less than one because you currently gain 4 points per dollar there. Amex has a surcharge and no bonus. KF VISA no surcharge , but no extra points eiher.
And just to keep you on your toes for example does one go for:
a/ Fuel at Caltex with 4 cent/l discount voucher
or b/ Fuel at BP with bonus 1.5 points if paid with Amex issued Amex?
(ie what is a MR point worth to you?)
Unfortunatly this is where I lose out a little as I have a fully maintained lease for my car and fuel is included.
