Amazon Product In a Post Plugin Price Problem

Hi,

I am using “Amazon Product In a Post Plugin” to retrieve items from Amazon.
[AMAZONPRODUCT=xxxxx] is working well, but the price for “New from” is not the amount I am looking for.

For example,
https://www.amazon.co.jp/ARASHI-10-11TOUR%E2%80%9CScene-~%E5%90%9B%E3%81%A8%E5%83%95%E3%81%AE%E8%A6%8B%E3%81%A6%E3%81%84%E3%82%8B%E9%A2%A8%E6%99%AF~-DOME-%E3%80%90%E5%88%9D%E5%9B%9E%E9%99%90%E5%AE%9A%E7%9B%A4%E3%80%91/dp/B004ZVVA6I/ref=sr_1_1?s=dvd&ie=UTF8&qid=1312619553&sr=1-1

For this item, it is giving me the “5900 YEN” instead of “7800 YEN” as published on amazon webpage.
5900 YEN is the lowest new price, item selling by other sellers, not Amazon.
What variable can i use to change this to the new price Amazon had on its page?

if(isset($result["LowestNewPrice"])){ <strong><--What is the other alternative other than LowestNewPrice ?</strong>
                    if($result["LowestNewPrice"]=='Too low to display'){
                        $newPrice = 'Check Amazon For Pricing';
                    }else{
                        $newPrice = $result["LowestNewPrice"];
                    }

Thank you.
