Short Story ---
Use the URL below and modify the fields to get a coupon for your name, and desired expiration and 50% off at Yoshinoya.<p>I've fortunately found a way to sustain my "keep it cheap" startup eating lifestyle for just a little bit longer...Yoshinoya, a prominent Japanese fast food joint in the LA area offered a coupon when you sign up for their newsletter. In my inbox arrived a link to my coupon, that didn't seem to be tied to my account at all. Turns out anyone can access the link, and anyone can change the URL parameters so the coupon works for them...anyway, link is below -- enjoy...<p>http://yoshinoyaamerica.com/email1/october2010Coupon.php?firstName=Jason&lastName=Corwin&DA=September%2014,%202011<p>Enjoy!
