Funnily enough I purchased an Ergodox EZ after clicking through an ad for it. I actually see this a lot with "niche" products (audio equipment, home automation, keyboards, etc) where I will have never seen an ad for anything in that product category but once I start going to the hobbyist and store pages for such products I get inundated with ads for one specific offering in that category for a week or two before all of my ads go back to what the usually are.
