Many people are fans of e-commerce, which is a fancy way of saying going shopping on the Internet. You can find a greater variety of selections of things you want than at most stores in your neighborhood. You can also find lower prices.

To give a relevant example, here's how to buy For Dummies books from the Google Play Store:


From your Home screen, tap the Play Store icon.

The Play Store icon is located at the far right of the first row in the figure.


From the Play Store Home screen, tap Books.

The Play Store Home screen makes lots of suggestions.

You want to find more For Dummies books.


Tap the magnifying glass icon in the upper right corner.

You can type in the words For Dummies. You can also tap the microphone and say “for dummies.”

If you know which For Dummies book you want, you can also say the complete name, such as "Samsung Galaxy S 4 For Dummies."


When you're ready, tap the magnifying glass icon.

This brings up your options.


Click the thumbnail of the book you want to select.

Feel free to browse! (Please note that the choice shown is for the earlier versions of the Galaxy S line!)

When you are ready to purchase, tap the blue box with the price. If you have a credit card on file with Google through your Gmail account, it verifies that you want to buy.

Tap Buy, and the book is on the way to the address you have saved!
