Bought HP ink cartridges at Walmart. A month later HP called them out as "inauthentic" cartridges. I.E. fake. I bought mine at the Stanley Park store. Juts so that you know, if you buy em at any Walmart store, they are not guaranteed for the duration of the cartridge's print cycle. Since Walmart is obviously selling fake merchandise, your $60 ink could be worthless well after the return policy runs out. They will not accept returns of such merchandise.
Are you the owner of this business?
