I bought a pack of ink cartridges from Choice Stationery once, several of each, colour and black, after reading a recommendation. They were the worst cartridges I have ever known. I am only a light printer user and every one of them dried up while more than half full. I have never had this problem, before or since, using other cartridges, now on ones from SVP Communications.
I am a light printer user, I probably use my printer a couple of times a week most of the time, I am using cartridges from Choice Stationery, the ink never dried on me, I suppose if you don't use your printer for a few weeks, the ink eventually will dry out or the nozzle of the cartridge will get blocked. The only problem I had with the cartridges is lately when I realised that the ink was leaking and it left a couple of big black blotches on one of my printed pages, I just placed the cartridge back properly and I had no problems since. I have been to a shop where they refill cartridges and they are doing compatibles as well, when he told me the price for the 4 cartridges I needed, I nearly had a heart attack. And there was no way that they would give you a free cartridge if you take 2 sets of 4 like choice stationery do. I won't be buying any this time, as I ordered some the last time TOPCAT told us about some savings to be made, it was a month ago.
