When was the last time you bought something online? If you've forgotten the answer, then maybe you've been a little negligent about your cyberlife lately.

Nowadays, almost everything is done online. Online is how you pay bills, buy cat food, compare swatches of paint color, research about seafood and fifteenth century art, shop for used cars, watch uncut versions of music videos, ego-search your name, find a roommate and homes for rent, post classified ads for your slightly-used tennis racket, search for possible baby boy names, manhunt for a long-lost schoolmate in third grade, and endless other things you can do with a few taps at the keyboard and the mouse. The fact that you're reading this article online proves that you are very much in touch with the virtual world.

A few years ago, people used to describe cyberspace as a “place” people interact through computer networks. It's a boundless geography so to speak. Now cyberspace is no longer just a place where to do things; it has become the very way of life for us.

Enter online shopping. With hundreds of online classifieds that let you browse and post free classified ads out there, at least one of them has something that you're looking for. And sure enough, this treasure-hunting factor is what makes this buy sell trade popular and highly addictive especially among the MTV generation. Also, because of the freedom and autonomy it grants everyone. Now, everyone can take charge in buying and selling their stuff. Everyone is a cyberprenuer.

Buy and sell online now! Let's take cat food for example.

You don't have to leave the cat home alone. And the kids and your husband too for that matter. You can shop at the comfort of your own home, click at this and that classified ad, and get what you want.

No crowds. Which also means no squeezing your way through crammed supermarket aisles, no people elbowing you, or stepping on your toes, no long lines at the checkout counter, and no irate rival-customers to fight with for that last can of cat food.

You can do it in your pajamas. Comes in handy if you're feeling especially lazy to get dressed up just to inspect homes for sale or second-hand Toyotas or Volvos or all organic cat food. Simply browse classified ads and their photos and that's it.
