How LayerSpecs earns money
LayerSpecs is free to read. We earn money through affiliate links: when you buy a product through a link on our pages, the store may pay us a commission. You pay the same price as you would without our link.
That is why every article and page on this site starts with this line:
Affiliate links: if you buy through links on this page we may earn a commission, at no extra cost to you.
The line is the same for readers in the United States and in the United Kingdom. It opens with the label “Affiliate links” so that you know, before you read, that the page contains links that can earn us money.
Amazon Associates
LayerSpecs uses, or will use as soon as our application is approved, affiliate links to Amazon through the Amazon Associates program, and to other programs when we join them. We have applied to Amazon Associates (Amazon.com) and are waiting for approval, so until then no Amazon link on this site earns us a commission. Once we are approved, this sentence will appear at the bottom of every page:
As an Amazon Associate we earn from qualifying purchases.
Other affiliate programs
We may also join affiliate programs run by manufacturers and retailers, directly or through affiliate networks. Today the only program we have applied to is Amazon Associates, through Amazon.com, so for now the affiliate links on our pages go to Amazon. Readers in some other countries, including the United Kingdom, may be taken from Amazon.com to Amazon’s store in their own country, where a qualifying purchase can also earn us a commission. We update this list when we join or leave a program.
How we choose which links to show
- For the main product on a page, the link goes to Amazon for now. If we join other programs later, this page will say so and the order of links will follow the rule written here.
- Accessories, such as nozzles, filaments and build plates, link to Amazon.
- When a page shows more than one link, you can choose where to buy.
- Links are set once, in our product records, and not page by page. When we change a program, every page that mentions the product changes with it.
- Affiliate links are marked as sponsored in the page code.
The commission decides which link we show first. It does not decide what the page says about the product.
Prices
We don’t write prices in our pages. Prices change often and differ between stores and countries, so check the current price on the store’s page before you buy. If a page ever shows a price, it will come directly from the store’s own data, with the date and time it was retrieved.
Commissions don’t change the numbers
Every number on a product page comes from the manufacturer’s datasheet or manual, with the document and the date we checked it. A commission cannot change a number. If the manufacturer doesn’t publish a number, we leave it out instead of estimating it.
Comparisons end with a “pick A if, pick B if” summary based on those numbers. We don’t declare an overall winner. How we check the numbers is explained in How we verify.
Cookies set by stores
When you follow an affiliate link, the store’s website may set its own cookies to credit us with the sale. Our pages don’t set them. The details are in our privacy policy.
