When I bought a new HP printer in last spring, the computer store did not have the black ink cartridge I needed, so I purchased ink at Walmart. About 6 weeks later I inserted the new cartridge only to be informed that it was defective. I tried to return/exchange the cartridge at Walmart but was refused because a return must be made w/in 30 days of purchase. Lesson learned.
Since then I have replaced the ink successfully with cartridges purchased at Walmart.
Last Friday I noticed the print was light and the ink was low. I purchased an HP ink cartridge at Walmart, saving the receipt. On Sunday, I installed the cartridge only to ....once again...be told that it was defective. Tuesday I tried to return/exchange the cartridge. It took over an hour to get an response from a customer service rep. I was told that Walmart will not credit/exchange ink cartridges.
Warning to all....purchase your printer ink elsewhere.
