Ask HN: Best way to promote jewelry one ring at drastically reduced prices?

I'm looking to jump start some sales for some items on our Amazon account by getting a number of items 3 sales each, by creating a unique coupon code.<p>EX: http://www.amazon.com/White-Gold-Oval-Sapphire-Diamond/dp/B004HWKAVQ/ref=sr_1_51?s=jewelry&ie=UTF8&qid=1344023179&sr=1-51&keywords=gold+sapphire+ring at 30% off.<p>I have about 60 items I would want to do this for. I'm experimenting with Reddit, what ways would you recommend? The goal is to have three sales within a 1-3 day timeframe.
