AI-generated summary
For £13.66 ex‑VAT, an *original* Canon PFI‑5100 grey cartridge is the kind of price that looks “reasonable” rather than bargain-bin. The real question is whether you actually need **grey** in the first place, because inkjet-style consumables like this can get pricey if you’re not running the printer often or if your work rarely uses that colour. If your Canon printer is regularly producing greys for CAD, signage mockups, or proofing (where neutral tones and predictable output matter), this is a sensible choice—original ink tends to give more consistent colour behaviour than budget alternatives and reduces the headache of odd banding or profiles not matching what you expect.
I wouldn’t rush to buy it if you’re only printing occasional jobs or you’re happy with “good enough” colour. Also, if you’ve been burning through cartridges quickly, this one won’t fix the underlying issue—check usage settings and print modes, because most people lose money through over-aggressive quality settings rather than “wrong” cartridges. Bottom line: **buy this if you rely on accurate grey output and run volume**, otherwise consider whether you’d be better off spacing purchases or using a lower-cost option depending on how tolerant your workflow is to colour variance.
