This script can do anything.
Also they put their own google ads on your website, and you can´t change it.
For me not a fair FREE script.
To our knowledge we do NOT show google ads on your site, as part of our module/widget.
Yes the module/widget links to YOUR listing(s) on Listanza!. As part of the design, one manages their listings in only one place. That listing is then syndicated to Trovit, Overstock, and Vast, to name a few, as well as your own site. All in an effort to improve efficiency and effectiveness.
