I used to have a HP printer that used about 6 cartridges a year.
Now I have a Epson R200. I seem to be getting through them at a great rate, and in less than a month have used 3 and 2 more won't last much longer. Getting them from Choice means that they are a reasonable price and this usage is working out much cheaper than the HP. I suppose that the number of cartridges is due to their small size.
Now what I really want to know is, what am I supposed to do with this pile of used cartridges?
Unfortunately, no one that I know of will accept Epson cartridges for recycling. I have a friend who still puts all of his Epson cartridges in the recycling bin in Sainsbury's. What happens to them after that I don't know. Most Epson cartridges are now chipped so if you go down the refill route you will also need to get a chip resetter. I gave up refilling a long time ago due the mess. I get my cartridges from Choice for my R200 as well. I do quite a bit of photo printing and normal black text only printing. My cartridges last longer than a month though.
Regarding the Choice compatibles lasting longer, I would say that they may have slightly more content. I asked this question question about Lexmark compatibles,but Choice decided to ignore my email!.
Reference to Epson and chipping, I visited my local Curry's store last Friday, and purchased the last two JR Universal Zap-It cartridge chip resetter's, as a clearance offer £9.99 down to 97pence [yes 97p].Seems as though people are just not experimenting and refilling their own cartridges!.
