Fake Costco clearance?

We are Costco members for decades, and recently I stumbled upon an ad for Costco clearances. 

A bit surprised and suspicious I clicked on it to find out I was directed to a series of sites powered by Yahoo.com with stuff for sale coming from vendors other than Costco. 

So much for that offer and a good warning to me that just like fake news, the internet is chock-full-of misleading commercial offers. What one just needs to remember to check its provenance. 

If it doesn’t come from the falsely advertised company and you can kill it right here and there! We’re learning something new everyday...
