Lots of businesses in today’s modern world operate using an Affiliate Partner model, where affiliates, promoting and selling products on behalf of the business, receive a commission for each sale generated that is attributed to them. Commission can range from as little as a fraction of a percent for mega-high priced products, to 100% + for low priced loss leading products. Commission can be earned without a sale, purely for information provided, it is an extremely large playing field.
We too operate in this area, both paying commissions to our own affiliates, and receiving commissions from our affiliate product partners.
This model does not, in any way, affect the price of a product, it is a one size fits all scenario. If a product producer sells something at $100, then affiliates sell at $100.
This is by no means an exhaustive explanation, as there would probably be no end in sight for that.
This section is merely to explain our position in this area, as it is required by law to be open about this information.
