There are certain expenses involved in running a website, such as hosting the website and associated mailing lists.
In order to cover these expenses, and earn an income for the time involved, I have some affiliate links.
Where I place an affiliate link, if you click on, you go to a different website.
If you buy something from that website, when you click through, I may get a payment.
This will not cost you any more than it would if you had gone straight to the website.
By that I mean, if you searched for something through a search engine, and clicked on one of it’s suggestions. You will pay the same for an item you buy as if you clicked an affiliate link.
