The links or products used don’t cost the buyer any more than they normally would – the commission is taken from the retailer via the commission platform, and therefore is a little thank you from the retailer, for introducing my audience to a specific product.
Each individual blog post will declare the use of affiliate links when used as well as declaring if the blog post has been sponsored. You will find these declarations at the end of each post if applicable.
I also use a Shopr widget to showcase products that I recommend. Many of the items listed will use affiliate links, which is declared as such within the shop pages.
