Thank you for sharing your insights over the AA Product Sting Builder Extension!! I was also thinking of exploring the Adobe-owned Product String extension i.e. "Adobe Analytics Product String". Pretty much easy to install but seems like we have fewer customization options here. I am not sure how to set s.product - "events" and "merchandising eVars" when using this extension as compared to Search Discovery which gives the direct option. Do you know to add these "events" and "merchandising eVars"...
