£320.82 inc. VAT
AI-generated summary
At £265.04 ex‑VAT for a single yellow Brother TN-821XLY cartridge, this is *not* the sort of toner you buy casually. In practice, you’re paying a premium for an “original” cartridge, which can be worth it if you run colour printing regularly and you want predictable output and fewer hassles with smudging, banding, or annoying print-quality prompts. If your business is doing customer-facing documents (marketing, proposals, labels, reports) and colour consistency matters, the cost starts to make more sense.
That said, if you’re mostly printing plain internal documents, drafts, or you only occasionally need yellow, this price is hard to justify—you’ll feel it in the month-end print costs. For cost-conscious teams, it’s usually smarter to compare the total cost per page with compatible options (or at least check what your machine’s typical yield looks like in real use). Bottom line: buy this if you’re colour-reliant, want “set it and forget it” reliability, and you’ve already confirmed it’s the right cartridge for your specific Brother printer model; skip it if you’re trying to keep print spend under control.
