Just dropped into my inbox:
Thanks for your support. As you know, a one-day site like Zazz can only be successful because of the love and support from people like you.
We want to send you a big (virtual) "thank you". As a token of our appreciation, can we interest you in this offer? Free 4GB Class 10 SD card - just pay for the shipping!
Not much use to me, but I thought I might get some bites here! ;)
To clarify: The e-mail also said, "By the way, if you have any friends you think may be interested in this deal, you can go ahead and let them know as well. We won't get mad."
I am wondering about the fact that it says "SD", and not "SDHC", though. Those old 4GB SD cards have limited compatibility.
