Taking your subject line at face value: If I'd wanted fries I would have asked for fries. In fact it's the textbook example of Annoying Marketing. It's different from "Oh, good idea, I wouldn't have thought of that" or "Often purchased together with..." with links.
Doesn't really matter if one person finds it annoying or intrusive - those are the people that aren't buying anyway, they can go visit the sites of people that ain't selling.
