That rate is probably the best you'll get and if you're a customer, you don't pay commission. In any event exchange rates are set by BSP which manipulates the market somewhat.
What's the current mall money changer rate in the Phil's? Going on past personal experience wherei live over there I would guess about 66.5 in our local shop.
I paid my (HSBC) credit card today using online banking and the Pound's sell price was 67.40. A couple of hours later I withdrew some cash from my Sterling account and the (HSBC) cashier came up with a rate of 67.25. This was a bit better than either of the forex booths in SM who were offering 65 but not as good as in Manila this morning when a rate of 68.41 was on offer.
