Credit Card Class Action: Get More Money Back Using Your Digital Camera

If you traveled abroad anytime between February 1, 1996 and November 8, 2006, your credit card company probably owes you money, but how much? Under a class action suing credit card companies for double-dipping on foreign transaction fees, the best bet for getting your the money, if you don't have detailed records of all your foreign transactions, is making an estimate based on how many days you were out of the country. One good way for shutterbugs to figure this out, says Delicious Baby, is to look through your vacation/travel photos on your computer. Most likely, they have digital timestamps you can use to figure out how long you were away. Now figuring out your refund is as easy and fun as going through your old photos. The due date for filing claims at ccfsettlement.com is May 30th.

I wish! I've travelled enough to know that customs stamps your passport on a whim -- but if you ask for it, they'll do it

You must have gone to europe. In South America, one stamp missing in your passport and you can easily miss your flight trying to get out of the country.
