I just got a call from my bank (CBA) and a US$2.99 purchase from a US store occurred last night.
I used Hannants on 23 JUNE last!!
So I would suggest ANY use of the Hannants website for purchasing is going to result in fradulent activity!
The security person from the CBA confirmed Glen's comments that it IS Illegal in Australia for any online retailer to hold your CC details unles you give them permission by checking the box that asks you that.
She also confirmed that a seperate CC that is NOT linked to any other accounts is the way to go for online use.
