Personally, I'd be contacting the general manager or Shopzilla and asking them if they're aware of what their lawyer or legal department is doing. I've had run-ins with lawyers before who want to 'make their mark' by fucking with people against their own client's interest. If Shopzilla did want this, fine, fuck 'em, remove the link and move on with life. If they didn't want this, they now are aware that they have a maverick lawyer on the loose.
