Amazon does display certain widgets to help you find related items. For example, they have:
- Recommendations based on products you have purchased, rated, etc., on Amazon
- Recently view items based on products you have browsed on Amazon
- Related items based on your searches on Amazon
To the poster: can you be more specific in what you did?
My guess is that you went to Amazon and either did a search or looked at a product, etc., and you just forgot. Don't forget that if you do a Google search and land on an Amazon page, then obviously that becomes part of your recently viewed items.
