Selling us depleted toner cartridges

Just a word of advice to anyone buying toner cartridges... Always check the ink levels when you get home. I bought a brand new toner cartridge from Incredible Connection months ago and kept it in storage as my current toner still had some ink left. To my surprise today when I try using the new toner purchased months ago, the ink levels are low. That time I don't even remember where I put my receipt. I'm never buying ANYTHING from Incredible Connection EVER AGAIN!!!
