We saved over $60.00 priced the 4 cartridges everywhere and they were sold in 2 packages (3 color and separate black). Prices were great and they work perfectly in our HP 8715.
Initially had trouble finding my ink. Cartridge receipt to exchange for correct cartridge. The Manager reviewed 6 months of my purchases to locate the receipt and make the exchange. This was real customer service to me.
I replaced the old cartridges with the new ones and was disappointed that the new prints were so light they could hardly be read. I have never had this problem before and wonder if the black xl (which I have never before used) was the culprit.
I always buy the extra fill ink. I do quite a bit of printing for my crafts and for letter the XL seems to last much longer than the regular fill. The only problem is the cost !!
