Birthday Gift

One day, a large box arrived in the mail addressed to Noah. Surprised and excited he ripped the box open and found... a whole slew of gift cards and a note. Being realistic, Noah realized the joke and it was confirmed by the note: "One of these gift cards has money on it."

After a few minutes of contemplation, Noah decided that the most likely pile would be iTunes cards and set out to check each one individually. An hour later, an electronic gift card arrived in his email - all the cards in the box has zero value.

Now, Noah is pondering who will be the next lucky recipient of this generous gift.
