This widget provides a nice, optionally thumbnailed list of Zazzle products 
based on query parameters you configure it with, including the store, search 
terms and sorting mechanism. Unlike other Zazzle widgets, this one only uses 
the referral identifier that you give it, or none at all if you do not 
specify one (you know who you are — wink).
Additionally, this widget can be embedded into your posts and pages with a 
shortcode. These shortcodes look something like <code>[pizazz query=asparagus rows=8 
columns=3]</code>.
I use PCRE to parse the RSS feeds. If Pizazz does not work, make sure that PCRE 
is available in your PHP installation. It is available on most PHP servers.
Pizazz is multisite-compatible!
NOTICE: I don’t have a testing staff, and my ability to think of every 
potential problem is limited. If you have problems make sure to report them 
to me or I won’t know they exist for a long time!
