I had a list of many bulk shops that buy, but I lost it. Is there a listing somewhere of bulk shops? If so, can you link it for me? And if this info is in another post please let me know.
Not sure about bulk but what you can try is use /v +directory on the SMP you want to check. This doesn't work all the time but several players have set up a residence which lists (nearly) all the shops there. Usually divided into sections, so maybe also bulk.
