On the Web: Supersize Me

At a movie theater concession stand you'll hear, "Want to make that a jumbo for just a quarter more?" In an airport bar, you can get a bigger beer for just a dollar extra. Car rental companies will upgrade you to a nicer ride for just $7 more per day. You can add 32 gig of extra storage to your iPod for just $80. All these merchants know that getting you to spend just a little bit more will supersize their profits. The same is true on your website.
