Kindle and my comic book - part 2

With only 2 days left to my one-week promotional period, I'm watching numbers droop. Now, it could be just because of the holiday weekend (that's what I'd prefer thinking) or it's genuinely not getting the levels of interest I've been striving for all these years.
While I'd prefer thinking it's just because of the holiday weekend, I'll post the link again anyway: www.amazon.com/dp/B009315BQA and hope people pay attention to it.
I've been hoping friends and family would help spread the word, as many of them promised, but so far, there's been dead silence. Perhaps friends here would do me the honor? Just click the link, copy the address in the address bar and repost it in as many places as you can. Word-of-mouth advertising is by far the fastest way to spread news. Also, don't just copy the address and post it everywhere, please download, rate and review the book! Click the little "like" button on the page, too. It really does need the help rising in the rankings.
It was doing so well yesterday, but look at the rankings now:

date        Amazon Best Sellers Rank     ranking gain
8/29/2012      4,082                      4,082
8/30/2012      3,386                      696
8/31/2012      5,003                     -1,617

Unfortunate numbers, aren't they? So, please, do me the favor of helping regain the lost rankings by downloading, rating and reviewing the book.
