Here’s a new concept:

Carrotmob, a NYC environmental group, is holding a "reverse boycott" at Tarzian Hardware.

So what does that mean?

The group will bring hundreds of shoppers to Tarzian on Seventh Avenue in Park Slope, where they are expected to spend thousands of dollars at the family owned store.

Tarzian has agreed in advance to put 22 percent of the day’s profits towards energy improvements such as upgraded lighting and heating.

Carrotmob, a global volunteer group, has already staged events in San Francisco and other cities.

If you are interested in seeing this "reverse boycott" come on over to Tarzian on December 14th. See for yourself how Carrotmobbers green Tarzian.
