    I have been using the Internet since I was five years old, when my dad first sat me down in front of our

computer and connected me to the World Wide Web.

    I've always felt like a master of the Internet world. AOL Instant Messaging, MSN, Gmail, Facebook, Myspace - I've got it all under control. I thought there was nothing more to the Internet besides checking

my e-mail and wasting my time until I found out about electronic commerce (e-commerce): business on

the Internet. Do Amazon.com, Yahoo.com, or monster.com mean anything to you?

    My friends often said they got cheap textbooks on Amazon.com, or had a good deal on Steve Madden boots that were on sale at SteveMadden.com. Unfortunately for me, I went on with my "e-commerce-less" Web-surfing, unaware of all the deals I was missing out on.

    That is, of course, until my sister finally sold the idea to me.

    "Why are all these packages arriving in the mail for you, Katy?" I asked her one day. Strange envelopes had been put on our doorstep for weeks now, each one always addressed to my sister; and we all know

little sisters should never be getting more mail than their older siblings (兄弟姐妹)!

    "Oh, it's the stuff I ordered online!" she answered. I watched as she opened item after item. There was

no way our parents were letting her spend that much money - online or off!

"How much did all of this cost?"

    "Oh, only about $15 in all!" She said excitedly. "Everything on eBay is on sale! It's better than going to

the mall."

    I felt as if my whole life, there had been a giant store in my backyard that I had never known about.

That week, I ordered a used Spanish textbook for 10 percent of the publisher's price. A few days later,

I bought an iPod protector and a book or two from the wonderful eBay.com.
