I just set up an Amazon Associates membership on my blog, so when I review a book or recommend a product, you, my readers, can buy the item directly from Amazon from my blog post, if you like. I love Amazon and do most of my online purchases through them.
If you decide to do so, I'll make up to 15% off of your purchase.
You, of course, don't have to worry about my integrity when I recommend something -- unless you see me recommending Al (PudgeFascist) Gore's "An Inconvenient Truth" for anything other than kindling for your fireplace.
Yours in wealth.
