Mitch Lipka, dealnews columnist The devastation of the earthquake and tsunami in Japan has people around the world digging in to their pockets to offer what help they can to those whose lives have been torn apart. When there is disaster and people open their hearts — and wallets — scams are sure to follow. Whether it is hurricanes in the South, the gulf oil spill or the earthquake in Haiti, the scammers lied in wait. So, here are some tips from the Federal Trade Commission to help your generosity find the cause you are seeking and not some greedy scammer looking to take advantage: Be wary of people or groups making urgent appeals for money whether in person, by phone mail, email, websites or social networking If a telemarketer calls, ask the name of the charity if it's not provided right away and then ask what percentage of your donation will go to the charity. Follow-up on that, if you're still interested, by verifying the charity authorized that solicitation. Don't feel pressured to give out your credit card or bank account numbers; wait until you've decided that the charity is legitimate and you're comfortable. Be sure to get a receipt and record that your donation is tax deductible. Don't give cash and don't write a check in the name of the solicitor rather than the charity. For those who want to leverage their contributions to a legitimate organization, look to double your money with matching donations. dealnews, for one, will match contributions to the American Red Cross up to a total of $25,000.
