Hi gang! Thanks so much for your input. What I have gleaned from it is to have a more positive attitude. Looks like my 870 isn't destined for the recycle bin just yet. Joan, I did check out as many as six Costco's in my area and they don't sell them. I had noticed for over a year that they didn't seem to be available. But I wrote it off to the frequent turnover of products at Costco. I will try out the online companies that have been suggested. However I am still unsure about the less expensive ink cartridge knockoffs. But I really can't lose to much if I take the cost factor into account. I could always switch cartridges when I needed to do special photo work. Thanks again to you all. Bill
