£155.90 inc. VAT
AI-generated summary
Honestly, at £129.92 ex-VAT the Brother TN-3512 is priced like a “get it from the manufacturer” cartridge, not like a budget buy. If you run a Brother laser in an office where uptime matters and you need consistently clean black text (reports, invoices, admin docs), it’ll do the job reliably and with fewer surprises than cheaper compatibles. In practice, original toners are usually worth considering when your printers aren’t set up for lots of experimentation, or when printing quality has to stay steady month to month.
That said, if you’re chasing lowest cost per page and you don’t care about squeezing every penny, this isn’t the best “value-per-impression” option—£130 is the sort of price that makes people start looking at compatible/refill options. It’s also only a sensible choice if this is the correct TN line for your specific Brother model; otherwise you’ll be paying premium money for no benefit. If you tell me your printer model and approximate monthly page volume, I can give you a clearer view on whether this is cost-effective or whether you’d be better off with alternatives.
