Not eBay, i confess, but I'm after some information about seller reviews on Amazon USA.

I bought an item from a charity in Tennessee who provided absolutely first class service, well over and above the call of duty, and I have accordingly posted a glowing reference!

I now want to check what others thought of that seller, but I have no idea how to find their accumulated references - nor, for that matter, can I find anything else they are selling.

As a charity, however, it is possible that they have nothing else [currently] on sale so that would account for that problem.

How can I look for feedback for a specific seller, without having access to a current offer of theirs?

Thanks in advance.
