I took the unique string out of your link:

https://www.google.com/search?q=Casio+Men%27s

The resulting page shows me 2 ad links, from
Sears and Overstock.com. If you allow any of
the numerous ways that Google tracks your
movements online then they know who you are
and the returns are customized for you personally.
That can also apply to prices you see. If you don't
make efforts to maintain privacy then Google results
are of dubious value, as is their news. It's all about
what they think is relevant to you. And the way
they define "relevant" is in terms of what will keep
you browsing, buying stuff and clicking ads. That's
likely to be combined with various parameters
chosen by the advertisers: Maybe I don't see
shop.com because they only want to pay for ads
seen by particular demographics and not any ads
seen by unknown visitors.

An interesting comparison might be to find a
youngish woman who does a lot of online shopping
and see what returns she gets.
