Expired Genuine HP Stock – Why Is It Discounted?
This cartridge is being offered at a reduced clearance price because the date printed on the HP packaging has passed.
The cartridge is genuine HP and unused; however, ink is a liquid consumable and its condition can change with age and storage. For this reason, expired stock should not be considered equivalent to current-dated stock.
This clearance product may be a cost-effective option for customers still operating older HP OfficeJet Pro X printers who understand the nature of expired ink stock.
