So the past week I have been jumping on the daily Delivery Hero $14 off $20 deal and have been paying with my Coles Rewards credit card. I just checked my statement noticed that one of my DH transactions was based in Berlin and as such, I was charged an international transaction fee. All the other transactions were based in Ultimo NSW.
INTERNATIONAL TRANSACTION FEE -$0.09
DELIVERYHERO BERLIN DEU -$6.00
The fee was only 9 cents (1.5%) so it's not a big deal (especially when I've saved so much) and I won't be pressing on it. Just thought I should let other OzBargainers know and suggest using PayPal/28 Degrees to avoid this, even if it's an unlikely scenario.
Thanks for letting us know OP!
