Direct Debit
If you did have a large purchase during that short period, why couldn't you just split the payment between your other held cards.
But we're at a point in our life, that we don't do too much extended foreign travel at present and therefore foreign purchases are not that big of a deal. So if I've got an AMEX I'm happy to cop the 3% fee, as the point that I earn will equal 1.5c and I know I will get much much more value out of it then that, otherwise I will use my debit account (and forego points
) that is forex fee free.
