This industry must make money hand over fist and yet if you Think About It it isn't very practical.
Americans buy millions of cards in a given year. I went to buy a few cards the other day and they cost me $3.00 each. Seriously, what the hell is that? These are pieces of paper with cute sayings on them but we are willing to pay $3.00 for each one? And these are items whose useful lifespans are approximately 15 seconds. They are read once, and probably never thought of again a majority of the time. And people give cards for so many different occassions. Birthdays, anniversaries, get well, Just-Thinking-of-You, Happy-Second-Tuesday-of-the-Month, etc. This has got to be the industry to get in if you want to make tons of money. Hallmark is privately held and has sales of approximately $4.4 billion (some of that is non card related products). That's a whole lot of happy wishes.
