AI-generated summary
Honestly, this Canon PG‑512 “high yield” black cartridge is a pretty sensible buy **if** you’ve got the compatible Canon printer model and you mainly print black text documents. The high-yield angle usually pays off in day-to-day office use because you’re not constantly swapping cartridges, and the price you quoted (£18.12 ex‑VAT) sits in the “reasonable” zone for a replacement that won’t break budgets when printing steadily.
That said, I’d be cautious if you’re using the wrong type of cartridge or you don’t print enough. If your printer spends more time idle than printing, the “high yield” won’t really save you anything—you’ll just be paying more up front for ink that might dry out or age before you use it. Also, don’t ignore your reseller’s options around compatible cartridges/ink economics; for some sites, you can get better cost-per-page elsewhere. If you tell me your exact Canon printer model and your monthly page count, I can say whether this cartridge is likely good value or not.
