There is a list on Subetalodge but I wasn't sure if the list was of current items or ALL items that have stocked there.

I don't think there's an easy way to track this . You might try doing a google search limited to this site and black heart hollow and see if you can find the most recent retirements and the announcement that they were going to change the way they restocked it.

You might want to try looking at this thread. While it's not directly what you are looking for, you can get a general idea of what items still stock there from looking at the most recent posts. :)

Thank you both! I'll try looking with both those methods.
