The following is an excerpt from The 7 Keys to Marketing Genius by Michael Daehn

Try your product in a test market before you fully develop it. The results may help you determine whether you should double production or scrap the project altogether. If you are thinking of carrying a new product line, try it out in some test cases first. One retail store I worked with tried a few bags from a company to see how they would sell. The product was very popular and we sold all the test models. The company worked out a deal and carried a large selection of the product from the vendor. In another case we carried another bag style that few if any people bought. We sent the rest of the test models back and said “no thanks.” If you have the ability to test market, take advantage of the opportunity.
