To be upfront, I do have affiliate ads on this site. What this means is that when a reader clicks on the ad or link, a new window will open, and they will reach the product page. If they like the product and purchase it, I will receive a portion of the sales price. However, this does not cause the reader to pay a higher price. They will still purchase the product at the normal price, and I will receive a percentage of it for being a referral. This is most commonly done using posts on a book review, which will link to the book on Amazon.com.
