after many hours of playing 
i found for the first time a unique weapon in a vending machine(Jack-o’-Cannon)
i even didn’t know this was possible
The last time I played I found it too. It was a nice surprise.
They show up in vending machines in TPS often enough that I always make it a point to check them (not so much in BL2). That said, I seriously didn’t think the Jack O Cannon could be obtained that way? Like you get it from the Halloween event or the SHiFT code, period. In theory, that means it’s available as a world drop?
