Costello's Ace Hardware of Mercerville is a great place to find things not available at the big box stores. The staff is always helpful, friendly, and very knowledgeable, providing excellent service. Customers prefer it to the large chain stores, especially for needs like keys, key fobs, paint, grills, and gardening supplies. It offers helpful customer service, a wide range of products, and the valued convenience of human interaction. Many recommend trying it for parts and other hardware needs.
