I'd like to search Amazon.com for products that Amazon sells without having to see all the third party merchants products. I've tried using some userscripts and some chrome extensions that claim to do the job but none of them seem to work. I prefer Chrome, but I can use FF for the searches if someone knows of a FF fix that actually works.
The easiest way is to add &emi=ATVPDKIKX0DER to the end of your search. Just perform your search, then click in the address bar and paste that at the end and hit enter and you'll get only items sold by Amazon.
If you want a shortcut to do this, right-click on your bookmarks bar in Chrome and choose "Add Page". For the name call it something like "Sold by Amazon", and for the URL put the following in
Now after you perform a search, simply click that shortcut on your bookmarks bar and it will reload the search automatically but only show items sold by Amazon.
Tip: by default Chrome doesn't always show the bookmarks bar. To show it all the time, open a new tab, then right-click the bookmarks bar and click "Show bookmarks bar".
