PURPLE SMARPHIN
Your compete MICRO*scope for today

You are the type of person who excels on exams, IQ tests, and mental puzzles. Family and friends generally call the local library when they can't find you, and rightfully so. Today, you are likely to spend a great deal of time touring the new suburban shopping complex wanting to buy either a set of hubcaps or handcrafted decorations to hang on your walls. Be on the lookout for vindictive digital clocks with revenge on their minds. You should consider shopping at stores or businesses beginning with the letter F, but do not buy any products with a serial number or product code containing the number 404009. Your preferred shopping venue is the Internet. Your special symbol is the exclamation point (!).


Is this You?

As a Purple Smarphin, you are the brightest and most intelligent person you know. And that goes for shopping, too. You know exactly what you want. You know exactly what it costs. You know exactly when and where to buy. But, of course, shopping is only one of the many activities that attracts your intellectual attention. You shop when you need to and buy if have to, but shopping is not the end all of your life.
