I don’t know to what extent this experience is shared by others. However, I have observed that there are players who want to acquire a very specific item from the BLB, but unfortunately do not always start Conan Exiles every day because of it. Maybe, we as a community here, will manage to maintain a kind of service by players for players, where everyone can regularly upload an up-to-date screenshot of the current offer in the BLB.
I will make the beginning:
The respective screenshot should always be as up-to-date as possible. Based on the date and time of the corresponding post, everyone can then assign how up-to-date the current offer is.
And please don’t misunderstand me. I don’t think I can somehow maintain this on my own in the long run! So if one of you is currently playing Conan Exiles and is in the forum by the way, you might take this opportunity to take a look here and see if there is already a current screenshot - and if not, just take it and put it here.
It would also be important to emphasize that this thread should remain clear and functional. 
Please refrain from expressing opinions, praise or criticism about the Black Lotus Bazaar and its contents. 
This can and should be done, but then please separately, as this would only lead to the fact that you might quickly lose track of the original function here, if you only want to check the current offer in BLB.
EDIT: DanQuixote was so friendly and opened an opinion thread about Conan Exiles’ Black Lotus Bazaar of a general nature in our forum here. You can find it here or directly at the end of this post.
2nd EDIT: Pugilist was so kind to add a post to this thread with an XLM-based file that documents the items offered in the BLB along with their price history. If you click here you will jump straight there.
As I mentioned before: Each regular Funcom forum user is only allowed to post a certain number of times successively in a thread.
