Costello's Ace Hardware of Princeton is a locally-owned and operated neighborhood hardware store. It is known for being "the Helpful Place," offering personal service, quality products, and a convenient shopping experience from local experts. The store carries a wide and excellent inventory, including many specific products and parts that can be hard to find at larger big-box stores. Reviews consistently highlight the friendly, nice, and super caring staff who are extremely helpful and knowledgeable. Customers report receiving efficient, immediate, and personal service, with staff going out of their way to hold items and help find exactly what is needed. The store also offers the convenience of online ordering. While most experiences are very positive, with customers stating you won't be disappointed, one note mentions that the staff quality has changed compared to previous ownership. However, the store remains a dependable neighborhood resource where helping customers is the most important task. Many express appreciation for having such a helpful, locally-owned hardware store in the community.
Another very satisfactory visit to the store, this time helped by Mike who was very patient to offer information and then helped to get the item.

I like a lot to go to Ace at the Princeton Shopping Center. The last time, Christine at the cashier was exceptionally kind and made my day with her attitude.
