At Visible Cities, we sometimes use URLs that pay us when you click through or buy the product. You will find a disclosure at the end of any post where I have inserted affiliate links. The Amazon link in the header is an affiliate link. I find using an affiliate link to be a much fairer way than inserting intrusive ads to sustain an income. It also gives me the freedom to recommend products I truly believe in. If you have any concerns, do mail me at hello@visiblecities.co
