Some links are to Amazon check-out pages : you think you are clicking on a link expecting to see a page explaining what a electrical-doodad is, but if you do it takes you to the Amazon check-out page to buy a that doodad , if you have an Amazon account it would be very easy to buy doodad by accident.. If not scam then sharp-practice. If Amazon links are necessary [ to earn commission on sales] they should to be to the product-description page, not the check-out page.
