Has anyone done this? They just sent me this email for my DS2. You have met the initial screening criteria to become a Nike Product Tester! Please print, read, and sign the Agreement, Release and Waiver form. You must submit both pages of the Agreement, Release and Waiver form with a handwritten signature to complete your application process. Please return both pages to Nike, Inc. via U.S. mail (Facsimile and electronic files will not be accepted) within 10 Business Days I'm wondering if I should go ahead and send it in? How long before you got your first tester of shoes? How long do you keep them before you have to send them back? Sorry for all the questions, I'm just not sure about it. Thanks for any info you can give me about it.
