Thanks Airhead! After I called compubank last night and was told I definitely could NOT make my initial deposit with a card, I wrote them an email asking the same question and they wrote back today and said I could. (If anyone has any trouble with this, I'm happy to send you their email.)

Has anyone figured out a way to get the miles OUT of compubank that earns clickmiles without buying anything? I am happy to be able to get the full limit on one credit card going into compubank, but then what? I might as well just pay the card off and keep charging with my usual cards, rather than spending it through their debit card, right?

Can you use the debit card to put money into Etrade or anything like that (more miles!).

I'd love to hear any ideas anyone has.
