You can blag it.. they don't check the applications too thoroughly. Just add any domain that you own providing it is not a trademark, x-rated or otherwise dodgy.
Get cheap domain name and create blog with lots of original articles. Don't use trademarked names in your URL.
I've just registered and approved by amazon for a blogspot with 1 article. Maybe they didn't check it.
I have also registered amazon a year ago. Main thing is,i want to review like others. For review user need to purchase once and i don't have way of purchase option. Just sharing my status of amazon with you.
