Question about Canon imagePROGRAF PRO-1100 A2 Printer

It is unclear to me which ink cartridges are required for this model. Canon says: LUCIA PRO II ink cartridges: PFI-4100 MBK/ PBK/ C/ M/ Y/ PC/ PM/ GY/ PGY/ R/ B/ CO 80ml I can't find these. Will these still be included in the programme, how expensive will they be and will there be packs of several at a lower price?
