I’m near this guy and could do a bulk buy if interest is there.
I would not want Bambu brand spools because of the RFID chips. I would look for brands like eSun, Hatchbox, or overture.
He states that these have the chips removed.
I am not sure that $2 a spool is a reasonable price. I just brought in about 10 spools last week and when I am printing a lot I generate about an empty a day. For now I would hold off.
