AI-generated summary
I’ll be blunt: if you’re buying a Canon PGI-550PGBK “pigment black” cartridge at around £12.04 ex-VAT, you’re probably paying a pretty normal price for ink—but you’ll only feel it’s good value if you actually print a lot with your specific Canon photo/business inkjet. Pigment blacks are the right choice when you care about crisp text, smudge resistance, and prints that need to handle handling better than dye-based ink. In the real world, that makes it sensible for docs, labels, and anything that gets touched or archived.
I *wouldn’t* buy it if you’re mostly printing occasional colour pages or you’re printing mostly for normal office drafts—then you’re often better off with whatever your machine is most cost-effective on. Also, sanity check that you’ve got the correct Canon model range and that it’s the PGI-550 series your printer expects; ink incompatibility and “wrong cartridge” buys are a quick way to waste money. For the right workflow (frequent monochrome/text output on compatible Canon inkjet systems), it’s a reasonable cartridge—otherwise it’s easy to overpay for what you actually need.
