Do we need to have a talk with your mom?

One thing I do with a lot of travel certs and such is email them to myself. I travel 4 or more months a year, and it seems that I'm on the road when the good deals come up. I stock up on the $100 NW certs whenever I can, and then email the numbers to me, then I make them used and save them, so I can tell how many valid certs I have left.
