Too many options are available making user performance slower. For instance, users of the product section are exposed to less relevant sub-sites such as support, about Microsft, and events/training. This makes the overall page more complex than it has to be.
Amazon.com has decreased their store tags from about 15 to 5 (Today's featured stores). Unfortunately, the featured stores are unrelated (e.g., books and kitchen). Amazon.co.uk offer 10 unrelated options.
To Amazon's credit, they have produced buttons that users interpret as clickable.
