I have one and I usually use ebay for replacement cartridges. The best thing about this is, paypal keep your money for about 3 weeks. If you are not pleased with the cartridges just put in a complaint through ebay and get replacements or your money back.Good luck..bestdriver
I had a Lexmark printer 12 years ago and used to regularly refill the cartridges. I now have an HP printer and am still refilling the cartridges.
I have just refilled the same pair of cartridges for two years at a total cost of about £5.
You can get refill kits for about £2.99 so it could be well worth a try at refilling.
