Curious what you all think about an affiliate page of mine

On average, this particular page is bringing in 300 purely organic visits each day. The problem is, I'm only averaging about 0.8 sales/day, which is less than a 0.5% Conversion rate. I'm relatively new to the affiliate world but I do know I could be doing much better.

What am I doing wrong here? Any tips or pointers (however basic or scant they may be) would really, really be appreciated.

I'm not 100% on this but in my mind it seems placing the "sales bait" at the bottom of the article would give better conversions since the reader has time to get comfortable with the author.

Again, any nudges in the right direction without giving too much away would be awesome.

Here's the page: http://tinyurl.com/

Thanks,
