Yeah, I've used it at least three or four times, now (possibly more).
The trick is to not log in to the site and just make a "guest" order. They can't seem (or care) to know if it's been used multiple times for a single address.
In a more amusing note, during the order process, I somehow managed to switch language preferences from English to French. I didn't want to take the time to switch back in case I missed out on the figures.
