You can help the victims of Hurricane Katrina by donating to the Red Cross, either online or by calling 1-800-HELP-NOW. You can also find other worthwhile charities that are providing food, shelter, and medical assistance at Charity Navigator, or at FEMA.
Note: luckyscent is donating 10% of all September profits to the Red Cross.
Update:
Perfumemart is auctioning off selected fragrances on ebay; all proceeds of the auctions will be donated to the Red Cross.
La Creme Beauty is donating 10% of all sales in September to the Red Cross.
Last night I stayed up late watching Katrina's doings on CNN. My thoughts are with all of those in the South who have been affected by this major hurricane.
