The FTC has recently issued guidelines for disclosing paid incentives for testimonials on amateur blogs.
Welcome to my amateur blog. I get paid nothing to write it. I get paid nothing to promote any products that I promote on this blog. I do not get free merchandise from any vendors that I endorse on this blog. However, if any vendors would like to send me free merchandise in exchange for an endorsement, I am happy to shill your product. Unless it sucks, because I do have standards, you know.
