If you’re not worried about buying non-branded ink cartridges then there are some serious bargains to be had. I’ve found a store – Phoenix Direct – which, if you buy the cartridges in bulk, work out at around £2.50 per cartridge (based on a black Epson Stylus C42 cartridge). The official cartridges retail at up to £18 – you do the maths.
You do have to buy them in bulk to get the best value but even individually black cartridges are around £3 and colour at £4. This company supplies one of the local computer shops and I’ve been using one of their cartridges this week – it works just as well as the official ones,although the driver complains about it being non-Epson the first time you use it.
