Availability of inks for Canon Pro-1 (UK)

Availability of inks for this printer seems rather patchy here in the UK. My usual supplier (Internet Ink) let me down badly (by claiming it was in stock when it was not, accepting my order and then when querying why it hadn't arrived, told me it would be another two weeks) and Canon themselves are quoting quite long delivery times. I've just managed to catch Amazon with their last few.

Not very good for Canon's flagship printer, good though the printer is.
