Are there any boards out for this?

BHH restocks a single item at a time from its item pool, randomly throughout the day, so there's no ping group since anyone who happens to catch a restock there is probably going to buy it.

But there's a ping group for TS restocks, the thread is here and the group is tsrestock. I would try searching for "restock" in the forum groups page since the search is touchy and doesn't seem to search the hashtags, only the descriptions

Cool thank you for the info
