General Affiliate Disclosure: 

I participate in affiliate programs with several products, websites, and brands.  An affiliate program is one in which the product owner pays me an agreed upon percentage of the sale price if one of their customers completes a purchase after clicking on a link that I provide.

In the context of an endorsement, I do my best to only link to products that I have personally used or have direct knowledge of.

Affiliate links to products, however, does not necessarily indicate endorsement.  An example of a non-endorsement related affiliate link would be in the context of lists of items that I have sold in the past.

Some companies with whom I have affiliate relationships with require specific verbiage in an affiliate disclosure.  Those are provided below.
