A man bought 12,150 pudding cups in one weekend so he could rack up enough airline miles to fly to Europe.

For once, a fun story in a chain email is actually true! As part of a promotion, Healthy Choice was offering 500 frequent flyer miles to anyone who purchased 10 Healthy Choice products. David Philips recognized that if he purchased individual cups of pudding at 25 cents apiece he could easily rack up a lot of miles. He ended up with 1.25 million frequent-flyer miles for roughly $3,000. That's the equivalent of 31 round trip tickets to Europe, or 42 tickets to Hawaii! He also donated the pudding cups to the Salvation Army and local food banks, and was able to write off the donations on his taxes.
