Have you ever designed a website or paid to have one done? The "apply coupon" code is standard on every checkout I've encountered, and I shop online a lot. lol.... You can bump this thread til the cows come home, you will not get a coupon code for that box, guaranteed....
In fact, if you know anything about java appletts, anyone can drag and drop a coupon code applet onto a website.... it doesn't mean the merchant issues codes. I've seen ONE code from Nirvana in 3 years and that was strictly for members of a specific newsletter.
good luck!
