Buying the right ink for your Brother MFC 7840w printer

You have two main options when buying Brother MFC 7840w ink. You can opt for an original ink manufactured by Brother themselves or choose a compatible cartridge which is manufactured for Stinkyink by a trusted third party.

The biggest difference is usually price with compatibles costing far less. Compare the prices of any compatibles listed above for yourself. So why the price difference? Often, printer manufacturers keep the cost of the printers themselves very low, in the knowledge that they will make the money back on the ink they sell over the life of the printer. Positive product reviews from tens of thousands of Stinkyink customers tells us that our compatible ink delivers great print quality.

We offer a low-price guarantee on all original ink we sell. If you find it cheaper within 7 days, we’ll refund the difference. The Stinkyink compatible range offers the best value for money you’ll find from any UK ink supplier. Try us for yourselves!
