Bests & Worsts Reviews from Amazon

First, I want to say that I'm a very positive person and would never write a bad review unless I had a REALLY bad experience. I have purchased these ink cartridges for years from my local brick and mortar store. I have never had a problem with the cartridges. I thought I would start purchasing from Amazon since I purchase so many other items from Amazon! Once I finally got my printer to accept the cartridge, everything that printed smeared badly. I tried printing the alignment page twice, but it smeared as well. I have never had this happen with the cartridges I've purchased in the past or with my printer. The product is still under warranty, but HP recommended online that I contact the seller to return the item. I didn't open this item until almost 45 days after making the purchase, therefore I can't return it, since the seller has a 30 day return policy. I may have just received a bad cartridge, but if you purchase this item, please check it soon after purchasing to ensure it is working properly since you only have 30 days to return the item. I went back to my local store and purchased two cartridges and both worked fine. Update: I tried repeatedly to contact HP with no luck. The box states that the product does have a warranty, but I can't get HP to back that up. I have tried calling and I spoke to them on "chat" and they can't even tell me how to return the item to HP for a refund or exchange! I am completely out of the money I spent on this cartridge.
