£91.21 inc. VAT
AI-generated summary
For a Brother TN-421Y original yellow cartridge, **£75.36 ex-VAT** is pretty much in the “proper replacement” zone rather than the bargain-bin zone. If you’re printing colour documents that need to look consistent (sales collateral, charts, internal comms), the **main reason to buy the original** is reliability—less messing around with quality swings and fewer headaches with feed/print consistency compared to some third-party options. Yellow especially is where toner quality shows up fast, so original is usually the safer bet if you can’t afford reprints.
I’d **recommend it if you’re a business that wants predictable output** and you’re already running Brother kit that takes this cartridge (so you’re not experimenting). If you print colour occasionally, though, the cost per page can sting—at that point, it may be worth checking whether your printer is due for a higher-yield option or whether a compatible alternative actually gives you the savings without risking colour drift. Overall: **buy it when uptime and print consistency matter more than shaving a few quid**; skip/compare if you’re purely hunting lowest cost per page.
