Before beginning the study, we'll ask you to read an informed consent page. Next you will answer an initial questionnaire. Then, we'll ask you to "shop" at a web site and make a decision to "purchase" something. After that, you will complete a second questionnaire. Finally, we'll ask for your email address so that we can contact you in case you win the drawing.

WHAT YOU GET

We'll give away $75 to a randomly-selected participant—this may help cover the cost of your "purchase," so you can really get something you picked out! Or you can just keep the prize money. If you wish, we will email you a copy of our report.

We also hope you will enjoy helping out with this research at the University of Iowa.

YOUR PRIVACY

You will answer the survey questions anonymously. No information on who you are is collected on the survey form. The host site for the survey questionnaires, Zoomerang.com, collects cookies but you do not have to accept any of them. If you do accept them, they are not used in any way to identify who you are.

A shopping site may require cookies to shop on their site, so you can accept them for the purposes of this survey and then delete them if you wish.

The survey questionnaires are completely separate from the form where you can give us your email address to register for the drawing. So you can answer the questions anonymously and yet register for the drawing. You can even answer the survey questions without registering for the drawing.

Your privacy is never compromised in the study. It takes only a small amount of your time. And it's fun to do!
