@BettyB, I've learnt from my time on AFF that it's better not to post details on the forum where it can be quickly shut down because of large scale abuse. Seen this too many times.
I know that some business, like Telstra and AGL, for example, stopped the micro payments following on from the transactions associated with this promo a couple of years ago. But not all businesses have (yet) stopped the process. I'm using one large business to do micro transactions of .01 each time. Benefit for me is that it:
1) Get 5 QFF each time from Bankwest
2) Gets around the credit card surcharge for transactions.
Happy for you to PM me and I'll let you know which business this is for. But I'm not posting this information in this forum.
