Honestly, this looks like one of those “works perfectly until you need it less” ink buys. £12.40 ex-VAT is a fair price *if* you know you’re using a device that specifically takes the PGI-525 series and you actually run pigment black prints with any regularity. Pigment black is the right call for text-heavy documents and anything that benefits from sharper, more durable black output than dye-based ink—so if your team prints contracts, invoices, or internal documentation and you care about consistency, it can be good value.
But don’t buy it “just in case” or because it’s cheap. Ink cartridges are a cashflow trap when demand is irregular: if you don’t print often, you may end up with wastage from drying/clogging and you’ll feel the cost creep over time. Also, I’d double-check you’re comparing like-for-like—this is an ink product, but it’s shown under a toner bucket, which is usually a sign of catalogue/category confusion. If you tell me your printer model, I can say whether this is the right cartridge and whether it’s likely to be cost-effective for your print volume.
