Bizarre and confounding Amazon Assoc. problem..Products I link to don't get orders
I have a fantastic CTR from my website to Amazon through my associates links, somewhere around 25% (sometimes higher).
However, my conversion rate once on Amazon is abysmal, usually around 1-2%.
What's even MORE strange is that hardly any of the items I actually link to are being ordered. The only orders that I'm getting credit for are the ones for products that I'm NOT linking to.
Here's a screenshot of the totals for this year so far:

So basically, out of nearly 950 products ordered, only 25 of them were ones that I recommended.
Anybody have any experience with a problem like this? Am I missing something obvious?
My niche is guitars and related gear, and here are a couple URLs to really highly trafficked posts:

Any help would be greatly appreciated. Thanks in advance!
