shopzilla evaluation?

Hi, I was wondering if anyone could comment on any experiences they
had with Shopzilla. I had an experience that I may be interpreting
incorrectly. 

I was contacted by a recruiter located in Los Angeles while I was
still in Florida. I sent my resume to him and he sent it in to
Shopzilla (then Bizrate.com). I heard nothing back from Shopzilla.

In the meantime, I got to Los Angeles about 2 weeks later to start
working for Valueclick. It was at this time that I got an email from
someone at shopzilla inviting me to call and talk about an interview.

Now, it *seems* as if this was an attempt to get a resume and then
contact the candidate directly but I'm not sure. First, any serious
agency, puts their address on your resume before forwarding it on. In
my case, though, it would be rather easy to find my resume on the
internet. Second, perhaps something got lost in the recent switch from
bizrate to shopzilla but they still had the resume? Third, I can't be
sure that it wasn't just an internet search that found me, although
the email was worded in a way that the recruiter there thought that he
had talked to me before.

One thing that sort of seems odd about Shopzilla is that they cater
lunch for you - almost as if they don't want you to leave the building
during work hours or something. I think I'm probably just misreading
their intentions on this.
