Whether you are looking for a brand-new or second-hand hp 29c, eBay offers one of the largest selections available online. With 31 active listings at the time of this page's last update, you have plenty of choice across different conditions, sellers and price points.

The average price of $79.52 can serve as a useful benchmark: listings below this tend to be used or auction-style, while those above often include extra accessories, warranties, or are sold by professional sellers with high feedback scores. Always check the seller's feedback rating and return policy before committing to a purchase. If you need the item quickly, filter by "Buy It Now" to avoid the uncertainty of auctions. For used items, look closely at the condition description and photos — terms like "good", "very good" and "like new" can mean very different things depending on the seller.
