November 29, 2010 (San Diego) – Negative TV advertising by Wal-Mart didn’t dissuade members of the San Diego City Council from voting against Wal-Mart. By a 5-3 vote last week, Councilmembers voted to require a neighborhood impact study be conducted before a building permit may be issued for big-box vendors such as Wal-Mart that want to open stores over 90,000 square feet that sell groceries.
