Affiliate links

Many of you have suggested in the past that the SWLing Post join an affiliate links program.

The SWLing Post now participates in two affiliate advertising programs with two large retailers that still sell shortwave radios, the Amazon Services LLC Associates Program and the eBay Partnership, designed to provide a means for sites like ours to earn advertising fees by advertising and linking to these retailers of radio products. Many of our links now function as affiliate links. This means that by clicking on these links, a small percentage of the purchase price for goods you purchase from these sellers will help support our site’s running costs. We hope you understand, and are grateful for your support.

But please note that we will never create a post and product link explicitly to receive a commission. Additionally, we always try to include links to other retail options if they are available, as we support and freely advertise independent ham radio retailers. Thank you, too, for your support of these sites.
