£281.30 inc. VAT
AI-generated summary
At £232.10 ex‑VAT for an original Canon black cartridge, the first thing I’d ask is: are you buying it because you need reliability, or because it’s “the safe option”? Originals usually give you the best consistency (fewer weird print artefacts, more predictable yields), so if you’re running a business-critical printer for invoices, letters, or anything you can’t afford to reprint, this is the sort of cartridge that tends to behave. It’s also a decent fit for offices that don’t want the hassle of troubleshooting after a third-party spend goes wrong.
That said, if you’re cost-sensitive and you’re printing in volume, £232.10 can be hard to justify—especially if your totals come down to cents per page. Many companies could save money with compatible cartridges, provided they’ve tested one batch first and accept that occasional variability is the trade-off. If you tell me the printer model and roughly how many pages you run per month, I can help you judge whether this price is genuinely sensible or whether you’d be better off exploring cheaper alternatives.
