I've just discovered this thread and am rather glad I didn't see it earlier... I have used Audio Affair twice in the last month for online purchases and have had no problems at all with their service. My GS Novo headphone amp was ordered on 24 February, shipped on 26 February and arrived as promised the following day.
My ex-demo NAD C565BEE was ordered at lunchtime on 19 March and arrived at midday on the 20th. I was able to track the package online as soon as I received the 'shipped' email. Can't ask for more than that, really.
I would certainly use them again.
