I'm logged in. Accessing from surewest.net I can see the review from the link provided. No other customer reviews are listed. If I click customer review on the sidebar, I get one 5 star review ("splish splash for my new fishy affirmation!"). I don't see the 106 customer reviews you mention anywhere. And there are no spotlight reviews. There is a bunch of stuff under editorial reviews too.
Avg review is 4 stars (5+1)/2=4??
