You need to go to the list of shops
http://www.fabshophop.com/listofshops.asp
and find your starting location. They like you to start with the initial of your last name. Click on one of the shops and it will take you to their site. Somewhere (on most sites but not all) you'll find a hint as to where the bunny is. Some don't provide a hint and you just have to browse the site.
The bunny you need to click on it will say You Found It. That will take you to a page where you fill in your email address to submit it to show you've found the bunny. You will get an email as well. You can also log in to the site to see which shops you have been to as well as those you still need to go to.
I think there has only been a month or two when I have not found them all but some are more difficult to find than others.
