I sometimes link to resources that my family and I personally use and recommend and that I feel my readers would be interested in. I participate in a few affiliate programs including Amazon-if you should decided to purchase their products, the company pays me a small referral commission for the sale, which does not effect the cost of your purchase. With the exception of posts containing links to Amazon.com, all posts containing affiliate links will include a note at the bottom.
I very seldom do reviews and if I do I only review those items I think my family and I will love, or that I feel my readers would be interested in, and this will be stated clearly in the post. I never recommend a product or resource for the sole purpose of being compensated financially.
