Similar deal as before, seems to be a repeat end of the month thing, same promo code too as last time:
Get 25 AUD off when transferring minimum of 400 AUD or equivalent in send currency.
Use promo code GET25 when transferring until Dec 6th (GMT, midnite). Not sure if it can stack with referral for new users as the email said for existing (if you're new users and it doesn't stack though, the referral is a better promo).
And per other's comment, the deal is good if you're only transferring $400 AUD (or close to it) because Skrill rate is not that great, but all other transfer website without promo code won't beat that $25 with their rate differences for such amount. Credit to @devilbabies for giving example here (please note that with any exchange rates fluctuation the numbers might vary a bit):
