I'm sure most OzBargainers are aware of the various platforms that sell discounted eGift cards. I'm interested in knowing which ones accept AmEx cards for payment (for the purposes of meeting minimum spend requirements for sign-on bonuses).
To start with, Suncorp Benefits (the only one I currently have access to) does not.
Rewards Gateway does, but charges something like 3% as a surcharge, compared to Mastercard for example
